离散元法刚性桩复合地基承载机理研究

Study on the Bearing Mechanism of Rigid Pile Composite Ground with Discrete Element Method

采用可变形体模型的离散元方法,对刚性桩复合地基的竖向承载能力以及桩土共同作用过程中桩、土承担荷载比例的变化规律进行了计算分析.揭示了刚性桩复合地基桩土共同作用的承载机理,提出了合理确定刚性桩复合地基承载力的方法.

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 .
