摘要
多支撑地下连续墙的应用越来越广泛,但其加固机理尚不完善.运用FLAC3D软件对某多支撑地下连续墙基坑工程开挖与支护模拟,计算中采用摩尔-库仑弹塑性模型,墙体和支护结构采用结构单元进行模拟.通过计算得出不同开挖阶段的墙背土体沉降、墙体内力和侧向位移,为工程设计与施工提供参考.
The use of Multi-struts diaphgram wall is more and more broad. The simulation of excavation and support on one multi-struts diaphgram wall project is carried out using the software FLAC^3D. During the simulation, the Mohr-Coulomb model is used and shell elements are applied on the wall and strut structure. This simulation offers the settlements behind the wall, lateral-displacements and moment of the wall in every step. It is a reference for design and construction.
