基坑开挖对城市轨道交通盾构隧道区间影响分析

摘要

Combining with the engineering geological condition of a foundation pit,this paper used the finite element software established the con-struction model,through the numerical simulation calculation,analyzed the influence of foundation pit excavation to urban rail shield tunnel inter-val,provided basis for subsequent engineering construction.%结合某基坑的工程地质情况，采用有限元软件建立了施工模型，通过数值模拟计算，分析了基坑开挖对城市轨道交通盾构隧道区间的影响，为后续工程的施工提供了依据。
