| 摘 要： | 为了深入研究深基坑开挖中双排桩支护结构的内力和变形以及与土的相互作用机理，运用大型有限元软件ABAQUS模拟某高层建筑深基坑开挖全过程。通过三维有限元的模拟分析，对基坑变形和稳定的影响因素进行了讨论，从而提出了一些控制支护结构变形，保持基坑稳定的方法措施。

| Abstract: | ABAQUS is adopted to simulate the mechanical behavior and deformation for retaining structure of foundation pit with excavating process. In order to reaveal the deformation and internal force of surport structure, spatial nonlinear finite element analysis is carded out in which the excavation process is considered. Ciritical parameters are discussed in detail. The analytical results show that the investigation of simulation of excavation process is necessary in such complex problem. |
