| 摘 要： | 以煤矿储煤仓基坑工程为对象,结合工程现场实际,模拟储煤仓基坑工程施工过程中可能发生的非正常情况下的施工现象,借助有限元分析方法模拟基坑土体及支护结构在非正常状况下的受力与变形特性.结果表明:钢支撑没有预加轴力对围护桩的受力和变形影响较大;桩体嵌固深度不足对位移影响不明显,但对桩体应力增大明显.

| Abstract: | Taking foundation pit project of coal storage bunker as object, this paper simulates atypical situation in foundation pit construction of coal storage bunker combing engineering practice. Through finite element method, it simulates the stress and deformation characteristics of soil mass and supporting structure and foundation pit in atypical situation. Results show that steel support without brace pre axial force has great influence on stress and deformation of retaining piles, deficiency of piles~ embedded depth has no obvious influence on displacement, but has obvious influence on increase of pile stress. |
