Abstract

In this paper, a method is presented for estimating the bearing capacity of shallow foundations based on the Discrete Element Method (DEM). By applying Winkler-springs for accounting for the compatibility between soil blocks, the proposed method can estimate the state of stress at failure surface and the ultimate bearing capacity. For the investigation of the application of the method, example problems about shallow foundations on the single layer and two layers soil are analyzed.

본 연구에서는 얕은 기초의 지지력을 평가할 수 있는 개별요소법에 근거한 해석기법이 제안되었다. 제안된 해석기법은 토체 간의 거동에 관한 적합조건을 탄소성 Winkler 스프링으로 모사함으로써 파괴면에서의 응력상태와 극한지지력을 함께 구할 수 있다. 기법의 적용성을 검토하기 위하여 단일층 및 이층지반에 설치된 얕은 기초의 지지력 해석을 수행하였다.
