| 摘 要： | 利用正交试验方法研究了弹性模量、泊松比、内摩擦角、粘聚力等四个土体主要物理参数对支挡物水平位移、坑底最大隆起量、地面最大沉降等基坑开挖变形效应的影响程度。通过正交化设计将256次FLAC3D数值试验，简化设计为16次试验;应用FLAC3D三维有限差分软件对这16种情况进行计算，得出了每种情况下基坑开挖的变形效应。正交试验结果得出了各个参数在影响基坑开挖效应中所占的权重，对基坑工程的预测和支护设计起到了指导作用，并为土体参数反演问题提供了依据。

| Abstract: | The influence of four main physical parameters of soil properties including elastic modulus,Poisson's ratio,internal friction angle and cohesion on foundation pit deformation such as horizontal displacement of retaining wall,maximum bottom heave,and maximum ground subsidence are studied in this paper through orthogonal test.By orthogonal design,256 FLAC3D numerical experiments were simplified to 16 experiments.Then these 16 conditions are separately calculated using FLAC3D three-dimensional finite differenc... |
