地下连续墙开挖过程中力学性能分析

摘要

With practical projects as examples, this paper establishes 3D physical models of underground continuous walls and acting soil bodies via universal finite element software. In consideration of coordinated deformation and interaction between supporting structures and soil bodies, the paper analyzes angular displacement of foundation pits, pressure of wall soil, upheaval and resilience of pit bottom, sedimentation of surface soil bodies behind walls, changes of groundwater levels and stress distribution of walls, etc. to instruct construction of similar projects.%以实际工程为例,利用通用有限元软件建立地下连续墙与作用土体的三维实体模型.考虑支护结构与土体之间的协调变形和相互作用,对基坑分步开挖过程中基坑角部位移、墙体土压力、坑底隆起回弹、墙后地表土体沉降变化、地下水位变化及墙体应力分布等进行分析,可为同类工程施工提供参考.
