摘要
在地铁隧道区间相近范围进行深基坑工程施工,必然会影响隧道结构本身的受力平衡系统。为提前预判地铁结构及深基坑支护结构的安全性,采用可靠的计算分析方法将至关重要。在以此为背景的某一大型深基坑项目为例采用岩土、隧道结构专用有限元分析软件进行计算,数值分析基坑施工的各种工况对相近地铁隧道的影响过程,三维模拟计算评估基坑施工过程对地铁隧道结构的影响变化,其分析结论将对项目施工具有一定的指导意义。
The construction of deep foundation pit in the similar range of subway tunnel will inevitably affect the force balance system of the tunnel structure itself.In order to predict the safety of subway structure and deep foundation pit supporting structure in advance,it is very important to adopt reliable calculation and analysis method.In this paper,a large-scale deep foundation pit project is taken as an example,and the special finite element analysis software for geotechnical and tunnel structure is used for calculation.The influence process of various working conditions of foundation pit construction on similar subway tunnels is numerically analyzed,and the influence change of foundation pit construction on subway tunnel structure is evaluated by three-dimensional simulation,the analysis conclusion will have a certain guiding significance for the project construction.
