摘　　要：本文提出分层土中承台-桩-土共同作用非线性分析方法,分析了群桩的工作状态和破坏特性,讨论了荷载水平对桩土结点屈服顺序的影响,以及荷载由角桩向内极的传递规律,桩土荷载分担等问题。并经实例验证,本文提出的群桩分析具有较好的可行性。This paper suggests a method of nonlinear analysis for the mutual interaction -between the pile cap, the pile and the soil in the layered soils. In the analysis, the working condition of the group piles, their failure characteristics, the influence of the loading level to the yielding sequence of the pile-soil nodes, the transmittance law of the loading from the corner piles to the interior piles as well as the share of loading between the soil and the pile are all investigated and all are verified by concrete examples. The analyses of the pile group in this paper have good feasibility.
