摘要
为解决地铁隧道盾构施工中引发的地层位移、地面沉降、衬砌应力对周围临近地下结构的破坏等一系列环境土工问题,本文运用三维有限元法对太原市地铁盾构法施工过程中引起的地层位移和地面沉降规律进行了建模分析,取得了良好的效果。本研究对盾构隧道的合理设计和施工采取必要的防护措施都具有重要意义。
In order to solve a series of environmental problems caused by shield construction of metro tunnel,such as ground displacement,ground settlement,lining stress damage to the surrounding underground structure,this paper uses three-dimensional finite element method to model and analyze the ground displacement and ground settlement law caused by shield construction of Metro in Taiyuan City,and good results are obtained.This study is of great significance for the rational design and construction of shield tunnel to take necessary protective measures.
