Abstract

There are many limitations for ensuring structural stability of retaining wall. Especially, L-shaped retaining wall and gravity retaining wall need large space, and massive concrete, respectively. Assembled Earth Retailing (AER) wall was developed to overcome the shortcomings. In this paper, stability of AER wall is verified by field model tests and the 3D-numerical analysis. The results show that horizontal displacement of AER wall was reduced by maximum 67.84% for conventional retaining walls, and earth pressure acting on the retaining wall was reduced by maximum 73.19%.

옹벽 중 일반적으로 많이 사용되고 있는 L형 옹벽은 배면에 공간이 많이 필요하고, 중력식 옹벽은 단면이 크다. 이러한 단점을 보완하고 역학적 안정성을 높이기 위해 AER옹벽이 개발되었다. 본 논문에서는 현장모형실험과 3D 수치해석을 통해 AER옹벽의 거동을 분석하였다. 그 결과, 기존 옹벽에 비해서 수평변위가 최대 67.84%가 감소하였고, 토압이 최대 73.19% 감소하여 AER옹벽의 높은 구조적인 안정성을 확인하였다.
