摘要
Abstract
Based on the particle flow code theory,the elliptical particle was developed by using the clump logic in PFC2D(two-dimensional particle flow code )to simulate the soil arching of sand in Trapdoor tests. The influence of trapdoor displacement, particle shape, particle frictional coefficient and the width of Trapdoor on soil arching were also studied. Numerical results show that the soil arching appears with the movement of Trapdoor, the soil arching strengthens with the increasement of the ratio of axis of particle and particle frictional coefficient, and the soil arch-ing weakens with the increasement of the width of Trapdoor.关键词
