摘　　要：应用ANSYS有限元程序对双排桩支护体系进行有限元分析.对青岛市某工程基坑支护工程建立有限元模型进行详细的计算分析.采用有限元法进行双排桩基坑支护结构设计,不仅能有效地分析双排桩土压力分配问题,还能够准确模拟基坑开挖的施工过程;而且能够获得基坑周边桩、土体应力场、变形场等更为丰富的信息,为双排桩设计、施工提供了一定的参考依据.In present paper, the finite element program ANSYS was employed for the performance analysis of the double-row-piles retaining system. A finite element model was established to calculate and analysis the retaining system of a project in Qingdao city. The finite element method could not only effectively analysis the distribution of pressure between pile and soil, but also accurately imitate the construction of pit excavation. Furthermore, abundant information of stress and strain field of piles and soil were obtained as well as certain references were provided to the design and construction.
