Use of the dilatometer test to estimate the maximum shear modulus of normally consolidated Busan clay

ABSTRACTThe aim of this experimental study is to estimate the maximum shear modulus (Gmax) of normally consolidated clayey soils using the results of a dilatometer test (DMT). A series of DMTs was conducted at the Busan New Port and Noksan sites in South Korea. In addition, basic index tests, bender element tests (i.e., shear wave velocity (Vs) measurements), and standard 1-D consolidation tests were performed using the undisturbed specimens. The results demonstrate that the Gmax of normally consolidated Busan clays cannot be adequately captured by the horizontal stress index (KD)-based empirical formula. Therefore, a Gmax estimating formula for normally consolidated clayey soils is newly suggested in this study using the dilatometer constrained modulus (MDMT) and stress-normalized material index (ID). Most notably, the estimated Gmax values using the suggested formula are comparable with the measured Gmax of both this study and the previous study on normally consolidated clayey soils.

A New Hybrid Decision Making Framework for Prioritising Port Performance Improvement Strategies

ABSTRACT This study aims to propose a conceptual decision making framework for prioritising port performance improvement strategies. It can be achieved by the concepts of benchmarking-best practices using analytic hierarchy process (AHP) incorporating a fuzzy technique for order preference by similarity to ideal solution (FTOPSIS) method. The leading performer (i.e. Busan New Port) and the poor performer (i.e. Busan North Port) are analysed as real cases to demonstrate the feasibility of the proposed methodology. The findings from the case study reveal that the terminal operating company (TOC) 2 represents a strong desire to choose the given strategies to improve its performance, followed by TOC3, while TOC1 has the least intention to adopt the given strategies. Amongst the 30 strategies of a benefit feature, optimisation of yard stacking planning (S4) is ascertained as the most crucial one to be implemented, followed by optimisation of berth to yard operations (S27) and optimising crane availability (S2). On the other hand, the formal training/education programmes from external professionals (S7) is identified as the most useful strategy among the 8 cost items. The results yielded by the framework present the ranking of strategy options in terms of their preference to different TOCs, which enables decision makers to find optimal solutions to improve performance under their own dynamic business environments.

ITT Platform의 복화율 개선에 따른 효과 분석 : 부산항 신항을 대상으로

This study tries to evaluate the effect of ITT introduction in Busan New Port. The study used the estimation model of the number of vehicles required in accordance with the backhaul rate. The model used big data, COPINO e-document for one year in 2015. COPINO recorded the event such as truck ID, container ID, ATA, damage etc when truck arrived at gate. The study finds important information to estimate the required number of trucks for handling current ITT containers in Busan New Port: Daily throughput in Busan New Port is 1650 vans, especially night throughput recorded peak level in 1800 hours to 2400 hours, the throughput between adjacent terminals recorded high, i.e PNIT to HPNT. The transportation capability for 6 hours between terminals is from 4 vans to 7 vans. The required trucks are estimated 89 currently without considering peak level. If we change the back haul rate from current 20% to 40%, 60% and 80%, how much would the cost drop? It was discovered that, if it is raised to 40%, 60% and 80%, the number of vehicle required will be reduced from 89 (current) to 76, 65 and 59. It was also discovered that the total savings will reduce down to 12%, 25% and 34%.

Study on Efficient Port Environmental Management for Sustainable Port Operation (I): Case Study of Marine Environments and Natural Resources Impacts by Busan New Port Development

국가물류경제의 중축산업인 항만의 지속가능한 운영과 개발을 위해서는 인프라 확충을 통한 경쟁력확보와 더불어 대기오염, 수질오염, 소음 및 생태계 파괴 등의 항만환경문제로 인한 지역커뮤니티와의 갈등해소가 더 중요한 요소로 부각되고 있다. 우리나라 부산 신항만 개발사업의 경우도 신항만 공사용 바다모래 채취로 인한 어민들과의 갈등 때문에 항만공사가 중단된 경험이 있으며, 그 주요 원인으로 현행 어업피해조사제도를 포함한 항만환경피해에 대한 정량적인 영향성 평가법의 부재와 한계라 할 수 있다. 따라서 본 연구의 주목적은 우리나라 항만의 지속가능한 항만운영 및 개발을 위한 효율적인 항만환경관리에 필수적인 정량적 환경영향성평가 방안의 제시에 있다. 이를 위해 국내외 항만의 환경정책과 사례분석을 통해 전반적인 항만환경문제와 그 영향(피해)에 대해서 살펴보고, 피해를 입은 환경재와 서비스의 전체적 경제적 가치를 평가할 수 있는 경제적 가치평가법을 제시하였다. 제시된 방법론 중에서 부산 신항만 개발로 따른 정박지 지정으로 인한 해양생태계 서비스 피해 사례에 대해 보다 과학적으로 추정할 수 있는 Habitat Equivalency Analysis(HEA)를 적용하여, 예시적인 피해액을 추정하였다. 본 연구의 결과를 토대로, 제시된 항만환경피해에 대한 경제적 영향성평가방법론의 제도적 도입을 통하여 보다 효율적인 항만환경관리방안을 제시하였다. The sustainable operation and development of ports is a key industry for Korea's national economy. It is increasingly more important to resolve conflicts with local communities due to port environmental problems such as air pollution, water pollution, noise and ecosystem destruction while securing port competitiveness through infrastructure expansion. In case of the Busan New Port development project in Korea, construction has been temporally suspended due to conflict with local fishermen over marine sand mining for construction. A primary reason for this is the absence and limitation of qualitative port environmental impact assessment methodologies in Korea. This includes the current investigation of fisheries damaged by ports. Therefore, the main purpose of this study is to propose economic valuation methods for assessing environmental impacts that are essential for efficient port environmental management and for sustainable port operation and development in Korea. To do this, this study examines the overall port environmental problems and their effects (damages) through the analysis of environmental policies and case studies of domestic and overseas ports. Then economic valuation methods are suggested for total economic values (TEV) of damaged environmental goods and services. Among the proposed methods, Habitat Equivalency Analysis (HEA), as a more scientific data based method, was applied to estimate marine ecosystem service damages from the designation of Busan New Port Anchorages. Finally, based on the study results, more efficient port environmental management will be achieved through the institutional adoption of the proposed economic impact assessment methods for port environmental damages.

Relationship between a Port’s Reputation, Customer Satisfaction and Customer Loyalty

There are two objectives of this study: to analyze gaps in customer satisfaction and to test the customer loyalty gap on the basis of the reputation of Busan New Port. This study identifies the relationships between variables as well as the conceptual and operational definitions using prior research. Data was collected from 93 members of the International Freight Forwarders Association. The reliability and validity of the data was analyzed and the relationships between the variables were tested by analysis of covariance. The results are as follows: First, the reputation of Busan New Port means the abilities in which the port provides valuable benefits to international freight forwarders. The analytical results show that there is a gap in customer satisfaction between high- level and low- level reputation. Second, the levels of reputation are based on the gap in customer loyalty. This means that there are gaps in the friendly attitude of international freight forwarders and sustainable usage on the basis of the varying levels of port reputation.

Application of the dilatometer test for estimating undrained shear strength of Busan New Port clay

The dilatometer test (DMT) is an economical and fast tool that evaluates the stratigraphy and properties of soil. In this study, a series of DMTs, field vane tests (FVTs), and K0 consolidated-undrained triaxial compression (CK0UC) tests were performed to develop an empirical correlation for the undrained shear strength (su) of clayey soils from the Busan New Port site. The stress-normalized mobilized su(μsu/σv′) for both laboratory tests and FVTs is determined to be around 0.22, which is consistent with previous studies. The exponent m for overconsolidation ratio (OCR), which is in the relation of su/σv′=S·OCRm, is determined to be 0.83 by using the SHANSEP technique. Two different methods of estimating su are reviewed to make use of either the horizontal stress index (KD) or the bearing factor (Nc). Because the DMT results indicate that the Nc is linearly proportional to the material index (ID), representing the characteristics of soil, the empirical su estimating formula with ID is newly suggested in this study. According to the values for the mean absolute percentage error (MAPE), the empirical correlation with ID shows a slightly better accuracy than that using KD. However, a comparison between the values for the su that are measured and estimated by using two different methods shows good agreement in general.

낙동강 하구역 진우도 남측 해역의 해저지형 변화

Bathymetric changes were studied in the southern sea off the Jinwoo-do Island, which is one of the deltaic barrier is- lands surrounding the Nakddong river estuary. In this study, 16 bathymetry data sets were obtained from June 2006 to April 2015. Two narrow channels, the one lying between Jinwoo-do and Shinja-do, and the other one lying between Nulcha-do and Jinwoo-do extended into the eastern and western parts of the study area, respectively. The eastern extension of the channel con- tained a passage of mixed estuarine waters of seawater and river water discharged from the Nakdong river barrier and the west Nakdong River. The western channel connected the Nakdong River estuary with the Busan New Port via a connecting pier. Total volumetric changes of sediments in study area and discharge flow of the Nakdong river barrier were analyzed. Bottom topographical changes occurred mainly in the eastern extension of the channel. These changes were initially characterized by gradual erosion or deposition followed by rapid restoration. The total volume of sediment gradually increased from June 2006 to March 2013, but experienced a sudden decrease in October 2013 because of typhoon Danas. Few fluctuations were observed from October 2013 to April 2015. Analysis of the cross-sectional bathymetry of the north-south direction showed that the deep- est point of the eastern channel moved 100-130 m westward and 200 m northward between June 2006 and April 2015.

부산신항 용원수로에서의 퇴적물 용출특성에 관한 연구

In Yongwon channel, its natural flow of seawater is blocked by the construction of Busan New Port including the container berth. The channel was transformed into a narrow and long one, where it is possible that ships are only allowed to pass through the north-side channel of Gyeonmado located at the point of river mouth to Songjeongcheon. In addition, Yongwon channel is approximately 100 m wide on average and 3,600 m long, and has the highest slenderness ratio (length/width

수달의 식이 습성 및 부산 신항 공사가 수달 먹이에 미치는 영향에 대한 연구

The aim of the study is to investigate the food habits of the Eurasian otter, Lutra lutra, and to examine any effects of the construction of the Busan New Port (BNP) on the prey. The frequencies and bulk estimate ratios of the biological debris, taken from spraints collected seasonally during the period from 2005 to 2011 at 16 areas, were analyzed. As the results, it was demonstrated that otters prey mainly on fish but occasionally on crustaceans and gastropods, etc., and the Mugiliformes was the most preferred fish. Although fish debris was observed throughout the season, it was suggested that the amount of fish eaten by the otter seemed to be associated with the amount of fish inhabiting the study area, judging from the striking similarities in the pattern of seasonal variations in each order of the fish between the frequency from the spraints and the fish catch. On the other hand, the frequencies of most of the fish, crustaceans, and gastropods from the spraints decreased from 2010, indicating the decrease of the amount of the prey by the construction of BNP and the strong possibility of the decrease in the number of otters in the near future. This is supported by the other studies, such as one showing a sudden decrease in the number of spraints since 2010, recent decrease in the fish catch, and the increase of marine pollution at this study area.

최근 10년간 장기연속관측에 근거한 부산항 신항 인근 해역의 파랑특성

Long-term wave observation was carried out near Busan New Port and the major wave characteristics were analyzed. At Busan New Port, waves from south direction were predominant throughout the year, while waves from the west, developed at the north sea of Geoje island, appeared almost the same frequency in winter season, showing apparent seasonal variation. During the observation period, the significant wave height was mostly less than 1 m, but it reached its maximum of 8.0 m when typhoon Maemi passed on September 2003. Also, the seasonal variation was hardly observed except July. In contrast, seasonal variation was apparent for the significant wave period, whose peak ranges 4~5 s in summer whereas about 3 s in winter. The largest significant wave period was 15.56 s, observed on June 2003. Meanwhile, the annual variation was negligible for mean wave direction as well as significant wave height and period. Further analysis of the wave data acquired for 5 years at 4.5 km south, in the south sea of Daejuk island, confirmed high correlation between the two observation points in summer and vice versa in winter.

배후단지 수배송 효율화를 위한 동적계획 및 운영규칙 설계

현재 부산항신항과 배후단지 물류업체를 연계하는 셔틀운송에는 배후단지 물류업체가 독자적으로 운송차량을 보유하고 운용함으로써 자원소모의 중복성이 있으며 불규칙한 운송화물의 발생으로 화물운송에 매번 다른 차량이 투입되어 업체들이 특정 지역에 밀집되어 있는 단지의 지리적 효과를 충분히 활용하지 못하고 있다. 따라서 본 연구는 이러한 문제들을 해결하기 위해 동적계획을 구성하고 휴리스틱 방법을 통해 작업 스케줄링과 실시간 작업규칙을 구성하며 물류기업의 수 배송 계획에 풀링과 듀얼사이클링을 적용하여 셔틀운송에 소요된 자원의 감축효과와 효율성을 시뮬레이션을 통해 검증한다. The shuttle that currently connects Busan New Port to the logistics companies in the Hinterland has the following companies: first, resources are consumed redundantly as each logistics company has independent transport vehicles. Second, the companies are not taking advantage of geographical merits of clustered complexes because different vehicles are used each time due to irregular schedules. In this respect, this study had the following purposes to realize these solutions: first, heuristic approach was made for operation scheduling and real-time operating rules to configure the best possible dynamic plan. Second, the reduction of consumption of resources with the shuttle and the efficiency were examined through a simulation of pooling and dual cycling applied to logistics companies' shipping plans.
