Optimal design of deep stormwater drainage tunnels to address urban flooding in Korea

Deep stormwater drainage tunnels play a crucial role in mitigating severe urban flooding in Korea, particularly as climate change leads to more extreme weather events. These tunnels typically consist of an entrance reservoir, a circular reinforced concrete culvert with a flat slope, a downstream reservoir, and an outlet to a nearby river. In this system, the flow within the circular culvert is driven solely by the momentum of free-falling stormwater runoff. However, concerns have emerged within the Korean water resources engineering community about the drainage capacity of these tunnels, even with a substantial fall height of approximately 30 m. Intensified localized rainfall, the abrupt transition from flood waves to pressurized flow within the circular culvert, and trapped air pockets can also pose significant challenges to the tunnel’s drainage efficiency. Conventional design methods often fail to optimize the culvert’s diameter and spatial configuration, leading to suboptimal performance. In response, this study utilizes 3D numerical simulations with the interFoam solver from the OpenFOAM toolbox to address these issues. The results indicate that smaller culvert diameters—provided they do not exceed the maximum permissible flow velocity—enhance drainage capacity by reducing the impact of shock waves and stabilizing flow. These findings challenge the prevailing design practice in Korea, which holds that larger culverts inherently offer superior drainage capacity. Moreover, the simulations suggest that as culvert diameters increase, the size of trapped air pockets grows, further reducing efficiency. Although air chambers can help mitigate the retarding effects of trapped air pockets, their effectiveness diminishes if positioned near the origin of shock waves, where they risk being filled with stormwater. Based on these insights, several key recommendations are proposed: First, the design of deep stormwater tunnels should prioritize minimizing the extent of trapped air pockets, even when air chambers are used. Second, the current focus on detention capacity in design practices should be reevaluated, as excessive detention capacity may exacerbate air pocket formation. Finally, modifying the inlet channel to induce spiral flow within the entrance reservoir could reduce impulsive forces, lower maintenance costs related to armoring rocks at the reservoir bottom, and stabilize flow more quickly, thereby enhancing overall drainage capacity.

Numerical Modeling and Performance Evaluation of Carbon Fiber-Reinforced Polymer-Strengthened Concrete Culverts against Water-Induced Corrosion

Culverts fulfill the vital function of safely channeling water beneath railway tracks, highways, and overpasses. They serve various purposes, including facilitating drainage in areas such as watercourses, drainage zones, and regions with restricted ground-bearing capacity. Precast reinforced concrete (RC) box culverts are a popular choice because they are strong, durable, rigid, and economical. However, culverts are prone to corrosion due to exposure to a range of environmental factors and aggressive chemicals. Therefore, enhancing the design and construction of this crucial infrastructure is imperative to effectively combat corrosion and to adhere to modern standards of reliability and affordability. In this study, carbon fiber-reinforced polymer (CFRP) was used to strengthen corroded culverts, with promising potential to improve safety and longevity in these structures. This study compared the behavior of corroded RC box culverts to CFRP-strengthened ones using the finite element method (FEM). It explored the impact of varying the damage thicknesses owing to corrosion, ranging from 0 mm to 20 mm, on the structural performance of the box culverts. The results showed that the CFRP model exhibited a substantial 25% increase in the capacity and reduced the damage compared to the reference model. Moreover, a parametric study was conducted for establishing a cost-effective design, in which numerous CFRP strip configurations were examined for a damaged-culvert model. The results indicated that a complete CFRP sheet was most effective for the maximum design capacity and repair effectiveness. The study’s outcomes provide valuable insights for professionals engaged in enhancing the strength of box culverts, aiming to increase the capacity, enhance the stability, and strengthen corroded culverts.

COMPARISON STUDY OF INSTALLATION COSTS OF CONCRETE CULVERT TO MODULAR WELLS FROM POLYPROPYLENE PANEL

Pontianak City has a low ground elevation and a reasonably high groundwater level. The distribution of clean water from regional companies tends to be less than optimal, and there is high rainwater runoff, causing the channel discharge to increase along with the growth of land converted into residential and business areas. Therefore, houses often use fresh water storage, both raw and rainwater, to meet clean water needs. One type that is often used is concrete culverts. However, concrete culverts have gaps in the joints that have the potential to contaminate storage water. The development of modular wells can be an option that is superior in various aspects to concrete culverts. The results showed that installing polypropylene modular wells costs less than concrete culvert wells. In addition, the use of modular wells also has advantages in terms of ease of installation and maintenance, as well as efficiency in land use. Endurance strength Modular wells can carry a load of up to 24 tons/m2. Thus, the results of this study are expected to provide alternative methods of storing clean water in Pontianak City that are more effective and efficient in terms of cost and quality by considering technical and environmental factors.

Finite element analysis of ultimate bending bearing capacity for a multi-span extradosed bridge based on Willam-Warnke yield criteria

To investigate the load-carrying capacities at failure and failure modes of a five-span extradosed bridge with four towers, a solid element model was established using ANSYS. The model utilized the five-parameter Willam-Warnke yield criteria and was compared to calculations provided by the current specifications highway reinforced concrete, prestressed concrete bridge culverts (JTG3362-2018). The entire range of loads was analyzed, and the results were analyzed for accuracy. The average error in ultimate load between the finite element model and the bridge code was 6.5%, with a maximum error of 8.6%. Two methods were used to evaluate the ultimate load-carrying capacity of the bridge, both of which produced comparable results. It was discovered that the load-bearing capacity of the bridge was at a minimum when the load was placed on the midspan, with a surplus capacity factor of 2.14. Although the bridge meets the safety requirements of the current bridge code, it is important to consider this loading condition during operation and maintenance.

Multiscale finite element analysis of earthquake-induced damage on underground RC culverts: The role of reinforcing bar corrosion

This study conducted finite element (FE) analysis to investigate the effect of corrosion in the sidewall on the damage to underground reinforced concrete (RC) culverts under an earthquake. The rationality of the numerical model was validated through the analysis of quasi-static cyclic loading tests of corroded RC culverts. Based on the validated FE model, a nonlinear dynamic analysis of an underground RC culvert subjected to an earthquake was performed. Further, the global and local responses that were changed not only by the corrosion of the sidewall reinforcement, but also by shear reinforcement in the sidewall and magnitude of the earthquake were discussed comprehensively. The analysis results show that the global deformation of the underground RC culvert increases with a higher degree of corrosion of the sidewall reinforcement and that severe local shear crack damage can be concentrated on the concrete web when corrosion cracks exist. In addition, extremely serious damage was induced in the RC culvert when corrosion occurred in the sidewall without proper seismic provisions. Therefore, steel corrosion in an aging underground RC culvert with insufficient shear reinforcement should be closely monitored to prevent its collapse in the event of earthquakes.

A method to analyze the long-term durability performance of underground reinforced concrete culvert structures under coupled mechanical and environmental loads

The coupling effect of mechanical and environmental loads is the main cause of deterioration in the performance of reinforced concrete structures. However, most studies on the durability of reinforced concrete structures have focused only on mechanical or environmental loads. As a result, it is difficult to fully capture the effects of dry shrinkage and creep caused by temperature and humidity changes within the structure, as well as their impact on the overall deformation of the structure. To address this gap, this paper presents a numerical simulation of underground culvert projects using the DuCOM-COM3D analysis software. The results of the simulation demonstrate that this approach offers a more precise characterization of the porosity, temperature, and humidity inside the concrete, resulting in improved accuracy in predicting the long-term deflection, crack width, and other macro-mechanical indices of the structure. Despite these advantages, some discrepancies were observed between the calculated and measured long-term deflection values. Additionally, a limit analysis was conducted to investigate the potential causes of the large deformation observed in the measurements. Overall, the results contribute to a better understanding of the complex mechanical and environmental loads affecting reinforced concrete structures and provides a methodology for accurately simulating their long-term behavior.

Dynamic tests of the culvert face within crashtests

Severity of a vehicle impact into solid obstacles alongside the road can be annually illustrated through accident statistics. One example of such solid obstacles is drainage ditch culvert faces.

Rehabilitation Method of Culvert Foundation Failure using Polygeo Foam

A concrete box culvert with a dimension of 2.1 x 2.1 m and a concrete pipe culvert of 0.9 m diameter founded on soft soil were experiencing soil settlement causing undulation and discomfort to the traffic users. Voids that appeared beneath the culvert foundations triggering the road surface to sag. Objectives of the study are to assess the settlement of culverts underlain by soft soil using PLAXIS simulations on the initial subsoil conditions, after rehabilitation works with Polygeo foam injection and to evaluate the performance of Polygeo foam as a rehabilitation method. The settlement of the culverts underlain by the soft soil will be determined using finite element model based on the data and information obtained from geoforensic assessments including 12 nos. of deep borehole as well as soil laboratory tests. There were six culverts area undergone settlement problem, with two boreholes were executed at the side of each culvert. Throughout the five-year period of Post Construction stage with Polygeo rehabilitation works, the pipe culvert was shown to settle around 22 mm whilst the box culvert with pile settled around 14 mm. The study concluded that the rehabilitation works using Polygeo foam has been successfully reduced the rate of settlement and complied to JKR settlement criteria.

Performance Deterioration of Underground Culverts Considering the Effect of Dissolution and Its Impact on the Surrounding Soil

To address the problem of dissolution damage during the long-term service of concrete hydraulic buildings, the concrete dissolution damage degree D and contact dissolution loss model with time were proposed by combining the results of indoor concrete dissolution tests. A mathematical model of the evolution of concrete parameters with time was developed. In the context of an underground concrete culvert project, a numerical analysis model of concrete dissolution deterioration was established, according to which the effects of different damage locations on the stress and displacement of concrete culverts were analyzed. The results show that the settlement value of the surface and the soil pore pressure value increase more when the bottom of the culvert is damaged by dissolution, and the settlement of the surface from the bottom damage is about 1.07~1.16 times of that from the top damage. When the damage position deviates from the center line of the culvert, the maximum point of vertical displacement in the transverse settlement trough of the ground surface deviates from the centerline of the culvert by about 3~5 m in the horizontal direction. At the bottom of the culvert, the concrete permeability coefficient reaches 6.957 × 10−8 m/s~8.354 × 10−8 m/s in about 13~16 years after the occurrence of dissolution damage, and local leakage occurs, causing a significant increase in the pore pressure of the soil near the leakage location. The overall settlement and uneven settlement resulting from the dual action of dissolution deterioration of concrete and infiltration pressure can have a serious impact on the upper channel buildings.

Analysis of the Variation in Different Nondestructive Testing and Standards

Non Destructive Testing (NDT) methods are used to review or measure the materials or designs without annihilating their surface, item uprightness and future handiness. The overall objective of the research is to assess the strength of concrete in existing structures using Nondestructive Tests at Kachankawal Rural Municipality, Jhapa District of Nepal.Rebound hammer test and ultrasonic pulse velocity tests were used for determining the compressive strength of concrete. The existing Reinforced Concrete Cement culverts were used for 9 existing structures. Average rebound number were taken and calculated from each sample. From the average rebound number were taken to determine the grade of concrete along with corresponding compressive strength. Similarly, the Ultrasonic Pulse Velocity tests were done on same existing structures and path length and time were noted for assessing the corresponding compressive strength and the quality of concrete. Triangulation among rebound hammer test, ultrasonic pulse velocity test and proposed initial grading were validated using chi square test. Relation between compressive strength with rebound hammer and ultrasonic pulse velocity were analyzed using linear regression model. Chi square confirms variation in compressive strength between calculated compressive strength and standard compressive strength. The relation of compressive strength (y) at R² = 1 with rebound number (x) and ultrasonic pulse velocity (x) could be expressed as y = 0.9306x - 2.7233 and y = 2.904 x + 10.119 respectively. The study is a guiding tool for concern authority and professionals to make effective decision regarding further structural development and budget allocation of the existing structures.

Development and Evaluation of Top-Mounted Sockets for Weak-Post, Midwest Guardrail System on Culverts

New top-mounted sockets for use with the weak-post, Midwest Guardrail System (MGS) on low-fill culverts were developed and evaluated. The system was adapted from the MGS bridge railing for attachment to the top slab of a concrete box culvert. Three design concepts were developed and evaluated through dynamic component testing. Both lateral and longitudinal impact tests were conducted on the design concepts while mounted to simulated concrete culverts. Two concepts, a cylindrical concrete foundation and a steel tube socket assembly, proved strong enough to withstand the impact loads transferred from the posts without sustaining significant damage or displacements. However, the third concept, a concrete slab, fractured and allowed the sockets to rotate back without developing the post bending strength. Thus, only the cylindrical concrete foundation and the steel tube socket assembly in combination with the weak-post, MGS were determined to be crashworthy according to the Manual for Assessing Safety Hardware (MASH) Test Level 3 safety criteria. The new top-mounted, socketed, weak-post, W-beam MGS for low-fill culverts has multiple advantages over other guardrail treatments for culverts. The guardrail system has an unrestricted system length and does not require a transition when attached to the MGS. The top-mounted system can be placed parallel to the roadway with a constant lateral offset regardless of the position and orientation of the culvert headwall. Additionally, the attachment configurations were designed utilizing epoxy anchors, enabling the system to be installed on new or existing culverts. Finally, the sockets remain undamaged during impact events, allowing for quick repairs.

Predicting surface abundance of federally threatened Jollyville Plateau Salamanders (Eurycea tonkawae) to inform management activities at a highly modified urban spring.

Urban expansion has contributed to the loss of habitat for range restricted species across the globe. Managing wildlife populations within these urban settings presents the challenge of balancing human and wildlife needs. Jollyville Plateau Salamanders (Eurycea tonkawae) are a range restricted, federally threatened, species of neotenic brook salamander endemic to central Texas. Almost the entire geographic range of E. tonkawae is embedded in the Austin, Cedar Park, and Round Rock metropolitan areas of Travis and Williamson counties, Texas. Among E. tonkawae occupied sites, Brushy Creek Spring has experienced some of the most extensive anthropogenic disturbance. Today the site consists of small groundwater outlets that emerge in the seams within a concrete culvert underlying a highway. Salamanders persist within this system though they are rarely detected. Here, we model the occurrence of salamanders within the surface habitat of Brushy Creek Spring using generalized linear models. In the absence of available data regarding the amount of water that is discharged from the spring, we use accumulated rainfall as a proxy for discharge to estimate salamander abundance. Additionally, we present evidence of reproduction, recruitment, and subterranean movement by E. tonkawae throughout this site. Infrastructure maintenance is inevitable at Brushy Creek Spring. We intend for our results to inform when maintenance should occur, i.e., during environmental conditions when salamanders are less likely to be observed in the surface habitat, to avoid unnecessary impacts to this federally threatened species.

Slab Culvert Design as a Review

Abstract: Culverts are the monolithic structure made to pass across a roadway, railway lines etc. Soil strengthening is most to balance the flood water on both sides. It follows the traffic, water deigning, walking purpose, and any other activity is taken on culverts. The risk follow water level and up word and downward flooding is most important earth to reduce, water level reducing risk for the flooding. The structures to accomplish such water flow and traffic flow without any disturbance flow across the road are called culverts, small and major bridges depending on their span such as major span, lesser span it is totally depend on water flowing discharge. Culverts are commonly used both as cross drains for channel release and to pass water under a road at natural drainage and river crossings. Drains can be of changed forms such as circular arch, span, flat slab etc. Culverts can be built with different substantial material such as masonry, concrete, Bricks, stone or reinforced cement concrete. The structural elements are required to be designed to withstand to safety point and design structure and economical with all criteria are competed such as maximum bending moment and shear force. This research Paper provides full thoughts on the provisions in the Codes, design criteria, considerations and justification of all the above aspects on design. Culverts are required to be provided under earth embankment for crossing of water course like streams, Nallas across the embankment as road embankment cannot be allowed to obstruct the natural water way without any obstruction. The structural design involves consideration of load cases Slab empty, full, surcharge loads and design criteria are covered. And factors like live load, actual width, braking force, dispersal of load through fill, impact factor, co-efficient of earth compression etc. Applicable IRC Codes are compulsory to be mentioned in the examination and design of Slab ducts. The aim of this project is to analyse the Slab Culvert using STAAD PRO software. The structural basics of Slab Culvert are designed to resist maximum bending moment and shear force. The results obtained from STAAD in Research paper are almost similar to manual calculations as per the authors are suggested. The factor consideration cushion Depth, coefficient of earth pressure for lateral pressures on walls, width or angle of dispersion for live loads on Slab without cushion and with cushion for structural deformations are important items. The IS standard requirements in the design manual for roads and bridges (IRC-6-2000, IS 21- 2000) is used in the structural designing of concrete Slab Culverts. Keywords: culvert, types of culverts, IRC Condition, Software, Percent reinforcement, Pressure Cases, Side walls, Top slab.

Centrifugally sprayed Engineered Cementitious Composites: Rheology, mechanics, and structural retrofit for concrete pipes

Current trenchless rehabilitation techniques for deteriorated concrete pipelines have limitations in field operation, pipeline geometry and size, durability, and structural retrofit. In this research, an innovative technology utilizing centrifugally sprayed ECC (CS ECC) to retrofit cracked concrete pipes is established. Rheology is engineered by hydroxypropyl methylcellulose for viscosity enhancement, citric acid for rheology evolution retardation, and hybrid synthetic fibers for flowability control. CS ECC is demonstrated capable of building up to 50 mm thickness on both vertical and horizontal concrete pipes, with reachable diameters over 300–900 mm. A 25 mm CS ECC (5.7 MPa-tensile strength and 5.3%-ductility) lining enhances the cracked concrete pipe by 2.2 times in load capacity and by 1.5 times in deformation capacity. Combining the advantages of mechanical and leak-proof performance, low cost, fast construction, self-healing ability, and expansive coupling with host pipe, the developed CS ECC holds promises in rehabilitating concrete pipelines, tunnels, and culverts.
