Abstract This paper investigates the performance of four multi-objective optimization algorithms, namely non-dominated sorting genetic algorithm II (NSGA-II), particle swarm (MOPSO), strength Pareto evolutionary (SPEA2), and multi-verse (MVO), in developing an optimal reinforced concrete cantilever (RCC) retaining wall. The wall design was based on two major requirements: geotechnical stability...

A series of centrifuge tests was conducted to explore the earth pressures mobilised in loose and dense sand for a complete set active movement modes rigid retaining wall: rotation about base, translation top. Earth behind wall were measured by Tekscan pressure mapping system. This paper reveals that at all depths decrease simultaneously with while those shallow layers can increase linkage betwe...

본 논문에서는 BIM을 활용한 흙막이 시스템을 개발하고 소개한다. 선행 연구 분석을 통해서 BIM 이루는 기술들에 대한 조사를 바탕으로 요소 기술들을 개발하였다. 첫 번째 기술로, 및 표준 등을 활용해 BIM라이브러리를 구축하여 범용성과 재사용성을 확보하였다. 두 번째로, 토공 2D 기반의 물량 산출법들을 분석하고 시스템으로 활용하되 추가로 IDW 보간법을 활용하여 지형 생성 토공량 산출 구축하였다. 세 산출을 위한 4가지 수식을 제안하여 객체마다 각각 다르게 산출법을 적용하여 이후, 시스템에서 산출되는 물량산출서와 기반 물량산출서와의 비교와 검증을 시스템이 앞으로 나아가야할 방향과 한계에 대해 알아보았다.

A concrete block retaining wall is supported by its weight. This structure has some advantages, including lower construction costs, a water-permeable that produces less water pressure behind the wall, and more flexible because it can follow ground's contours. Rankine's theory usually used to design this wall. According theory, failure pattern forms an angle of 450 + • /2 with horizontal plane. ...
