摘要:基坑开挖导致墙后土体产生滑裂面，通过MIDAS有限元计算软件对万达广场基坑工程进行数值分析，总结硬化土模型的参数取值规律。结合万达广场深基坑工程实例，计算墙后土体水平位移监测点的变化曲线，对土体水平位移的变形规律加以分析。通过分析数值分析中得到的数据，分析基坑开挖的空间效应，结合工况对比分析SMW支护和双排桩支护下的空间效应比值的规律。
Abstract: Excavation leads to generate critical slip surface of soil.By MIDAS finite element calculation software, numerical analysis was carried out on the wanda square foundation pit engineering.It summarizes the hardening soil model parameter selection rule.Taking Wanda plaza deep foundation pit engineering as example, the calculation of horizontal displacement monitoring curve of soil analyzed the deformation law ofhorizontal displacement of soil.Through the analysis of the data, analysis of the numerical analysis of spatial effect of foundation pit excavation, combining with the working condition of SMW method analysis of supporting and double row piles under the support of the law of the spatial effect ratio.
