This paper mainly focuses on the comparison between the calculated value and actual value of the pile deformation, pile top displacement, and internal support axial force during the excavation of the deep foundation pit, and the influence of excavation method on the deformation. A three-dimensional space model is built using the finite element software MIDAS/GTS to simulate the excavation process of the foundation pit. It is found that the computed data are consistent with the measured values. On this basis the deformation of foundation pit supporting structure under different excavation methods is simulated and optimized to select the excavation method of the foundation pit.

深基坑变形监测分析与数值模拟

本文主要集中在深基坑开挖过程中桩变形，桩顶位移和内支撑轴向力的计算值与实际值之间的比较，以及开挖方法对变形的影响。使用有限元软件MIDAS / GTS建立三维空间模型，以模拟基坑的开挖过程。发现计算数据与测量值一致。在此基础上，模拟和优化了基坑支护结构在不同开挖方法下的变形，以选择基坑开挖方法。
