초록

일반적으로 높이가 높아짐에 따라 옹벽의 안정성과 경제성은 작아지는데 이런 경우 선반식 옹벽이 효과적으로 사용될 수 있다. 선반식 옹벽의 선반은 전체 토압을 감소시켜주어 옹벽의 안정성을 향상시켜준다. 이 연구에서는 일반적으로 선반이 설치되는 위치인 지표면으로부터 0.4H지점에 선반을 설치한 선반식 옹벽과 캔틸레버식 옹벽에 작용하는 토압분포에 대한 모형시험 결과를 수치해석 프로그램과 이론해를 이용한 토압과 비교하여 선반식 옹벽에 발생하는 토압 경감효과를 확인하고자 하였다. 모형시험결과와 유한요소해석 프로그램 및 이론해에 의한 토압산정 결과를 종합해 볼 때 선반식 옹벽은 캔틸레버식 옹벽에 비해서 수평토압이 감소하는 것을 알 수 있고, 선반을 설치하여 발생하는 토압의 감소효과는 뚜렷한 것으로 나타났다.

The retaining wall with the relieving platform can be constructed as an alternative to the concrete retaining wall in which the economic and stability are decreased as height increases. The relieving platform has the advantage of decreasing the total lateral earth pressure on the retaining wall and increasing the overall stability of the structure. In this study, model tests were performed to determine the distribution of the earth pressure on the retaining wall with and without the relieving platform which located at a depth of 0.4H from the ground surface. And model tests results were compared with analyzed results by 2-D finite element method and values driven from theoretical equation. As the result of this study, comparing model test results with those of numerical analysis and theoretical equation show that the reduction of the lateral earth pressure on wall was indicated clearly on the retaining wall with a relieving platform.
