本文以大连某地铁工地围护桩施工为例,通过运用FLAC3D有限元数值模拟软件,模拟了基坑的分步开挖的整个过程,并针对影响围护体系内力与变形的主要因素,调整了模型中的相关参数后重新进行模拟计算,通过对比分析,得出围护桩的内力和变形的主要影响因素及影响情况。
Taking the construction of a retaining wall for a metro station in Dalian as an example, this paper simulates the whole process of step excavation by using FLAC3D finite element numerical simulation software. According to the main factors that affect the internal force and deformation of the retaining system, After the relevant parameters in the model are re-simulated, the main influencing factors and influencing factors of the internal force and deformation of the retaining pile are obtained through comparative analysis.
