Abstract

Abstract: Based on the deep foundation pit construction on adjacent multi-arch tunnel of Jianggai Ｒoad，the finite element software named MIDAS /GTS was used to establish three-dimensional model to calculate and analyze the influence characteristics of multi-arch tunnel under adjacent deep foundation construction． Through the finite element simulation of deep excavation construction process，the multi-arch tunnel structure’s displacement，stress and strain could be got to analyze the influence characteristics under deep foundation pit construction． The analysis results could be helpful for similar projects in the future constructions．

Key words: deep foundation, multi-arch tunnel, finite element, influence characteristics

摘要： 以重庆江溉路隧道邻近的建筑基坑工程为背景，采用有限元软件MIDAS /GTS 建立三维模型计算分析深基坑施工对邻近连拱隧道的影响特性。通过有限元模拟深基坑开挖施工过程，从连拱隧道结构的位移、应力、应变方面分析基坑施工对连拱隧道的影响特性，分析结果为今后类似工程建设提供参考。
