Abstract
Three-dimensional finite element analysis has been carried out in order to study the response of retaining walls subjected to lateral earth pressure using ABAQUS/CAE. This study consists of analysis and design of cantilever, gravity type, and precast concrete retaining wall. It also shows comparative study such as distribution of stresses along with the deflection throughout the height of the retaining walls. The mathematical analysis procedure is adopted that entails selecting dimensions to meet the requirements of several codes and then evaluating the stability of the entire whenever the backfill load works on the wall. The stability of retaining walls in terms of sliding and overturning is evaluated. The three specified walls are then investigated using the ABAQUS software, and their behaviour is studied. In this analysis process, two components of the formed concrete wall; one is a base plate and another component is a cantilever sandwich panel, were projected. A headed anchor joins the prefabricated cantilever wall to the base plate, keeping the slab and wall together while also maintaining their integrity in the specific positions. The system requires a unique construction method for final assembly. Mainly two steps were followed for analysis: first, the different components for shear and bending moments, namely, heel and footplates, were designed, and then, the stability of the whole structure under load was evaluated. The ABAQUS program was used to simulate and analyse the stability of various walls, including traditional and precast concrete retaining walls. It was found on the basis of the observation that the prefabricated retaining wall is the most viable option out of the three as the stress and deflection in the former type are lowered.
Highlights
Retaining walls are being used to sustain steep or nearvertical backfills in practically most construction projects
By applying the precast panel, the problems such as air delay and deterioration of concrete quality caused by concrete casting in the existing retaining wall have somewhat been solved. e panel-type retaining wall is a construction method that protects and reinforces the strength of the original ground as much as possible
In the case of the cantilever retaining wall, the stresses and deformations increased as the height of the structure increased. e highest values of stress were observed in the arrangements with a more toe-less heel, whereas the highest values of horizontal deformation with more heel-less toe arrangement of the wall were observed. e highest compression was deemed to be located close to the stem and toe junction, while peak tension was located close to the shear key and toe as well as stem and heel junctions [18, 19]
