基坑开挖对邻近建筑物影响的数值模拟分析

Numerical Simulation Analysis on Influence of Foundation Pit Excavation on Adjacent Buildings

近年来,城市的快速发展带动了城市基础设施的不断建设,深基坑开挖对周边建筑的影响越来越受到重视。本文结合某紧邻地铁车站的深基坑工程,采用Midas-GTS三维数值分析软件,模拟分析了基坑开挖对既有地铁车站的影响,论证了开挖方案的合理性和地铁车站运行的安全性,并且提出相应的施工保证措施。

In recent years,the rapid development of the city has driven the continuous construction of urban infrastructure.The impact of deep foundation pit excavation on surrounding buildings has attracted more attention.Combined with a deep foundation pit project close to a subway station,this article simulates and analyzes the impact of foundation pit excavation on the existing subway station by using Midas-GTS three-dimensional numerical analysis software,demonstrates the rationality of excavation scheme and the safety of subway station operation,and puts forward corresponding construction assurance measures.
