摘要

深圳地铁三号线红岭中路站—老街站—晒布路站区间盾构隧道上下完全重叠1 045 m。为了研究重叠地铁盾构隧道施工影响规律,采用ANSYS三维有限元分析软件,模拟围岩、支护结构及开挖过程进行了计算模拟分析,论证了盾构重叠隧道“先下后上”的施工顺序的可行性,其结果可供设计及施工参考。

Abstract

The overlapping shield bored section of Honglingzhong road stationLaojie stationShaibu road station section on Shenzhen Metro line 3 is 1 045 m.The Calculation simulation analysis is made on surrounding rock, supporting structure and excavation course of overlapped shield bored tunnel, by menas of ANSYS 3D finite element analysis software.The construction program of “construct down tunnel first and then the upper one” is reliable. The paper can provide references for similar projects in the future.
