摘要
以邻近地铁车站14.5m的某基坑为背景,采用有限元方法对深基坑工程进行数值计算,模拟施工期间各种工况下的基坑与地铁车站变形情况,并对各阶段的位移进行比较。同时,设计了3种基坑支撑方案,并通过整体三维有限元分析进行支撑体系优化,以确定经济合理的基坑整体支撑系统。此外,分析了基坑距车站距离不同时,支护结构及邻近地铁车站的位移变化趋势。
In this study,a foundation pit 14.5 m near the subway station is taken as the background,the finite element method was used to calculate deformation of deep foundation pit and subway station under various working conditions during excavation construction,and compare the displacement at each stage.At the same time,design three kinds of foundation pit support scheme,and through the overall three-dimensional finite element analysis of the support system optimization,to determine the economic and reasonable foundation pit overall support system.In addition,the displacement trend of supporting structure and adjacent subway stations is analyzed when the distance between foundation pit and station is different.
