Midas GTS 3D Numerical Simulation Analysis on Influence of Foundation Pit Excavation to Subway Tunnel

摘要:

随着城市地铁工程的高速发展，地面建筑物基坑的施工将必然会对邻近的地铁隧道造成一定的影响，运用Midas GTS三维数值模拟计算软件分析基坑开挖对邻近地铁隧道的影响，对地层自重固结、基坑开挖施工的整个过程进行模拟分析，计算的结果与实际监测数据进行对比表明，该方法对实际工程有一定的指导意义。

Abstract:

With the rapid development of urban subway construction, the foundation pit excavation will affect the neighboring existing subway tunnel, this paper analyzed the influence of foundation pit excavation on adjacent subway tunnel with Midas GTS numerical simulation calculation software, makes simulation analysis of the entire process of stratum weight consolidation, foundation pit excavation, the results show that the method has certain directive significance to engineering.With the rapid development of urban subway construction, the foundation pit excavation will affect the neighboring existing subway tunnel. This paper analyzes the influence of foundation pit excavation to adjacent subway tunnel with Midas GTS numerical simulation calculation software, makes simulation analysis on the entire process of stratum weight consolidation and foundation pit excavation. The results show that the method has certain directive significance to practical engineering.
