摘　　要：采用自编弹塑性有限元程序,在弹塑性地基条件下对群桩-土-承台的共同作用做了数值模拟,对土的分担比、底板沉降、基底反力做了深入分析,得出了有价值的结论,对桩基设计具有较大的指导意义.The pile-soil- cape interaction is simulated with its own elasto-plastic finite element program on the condition of elasto-plastic ground and the soil＇s share, the floor settlement and contact pressure beneath foundation are analyzed in this article. From this analysis, some meaningful conclusions are drawn. It has greater directive significance to the pile foundation design.
