Abstract: In this paper, the bearing capacity of rigid pile composite ground under vertical loads and the law of variation of pile-soil bearing ratio among pile-soil interaction are calculated and analyzed on the basis of discrete element method of the deformable body model, which describes the bearing mechanism of pile-soil interaction of rigid pile composite ground. The method of how to ascertain the bearing capacity of rigid pile composite ground is presented .

Key words: rigid pile composite ground; bearing mechanism; discrete element method;
