基坑开挖中双排桩支护结构空间受力特性研究

摘要

Based on a excavation oroject in Qingdao,a three-dimensional FEM model of foundation oit double-row oiles suooorting structure is established using ANSYS in this oaoer. The soatial stress characteristics was analyzed. The results show under the same condition of total flexur-al rigidity,the oile too lateral disolacement of double-row oiles is less than 1/2 of single-row oile.%依托青岛某基坑开挖工程，采用ANSYS软件建立基坑双排桩支护结构的三维有限元分析模型，对其空间受力特性进行了分析，研究结果表明：单、双排桩在总的抗弯刚度相同的情况下，双排桩桩顶水平位移不到单排桩的1/2。
