摘要
文章针对某地铁工程区间下穿已运营的地铁7号线区间,分析在建工程施工引起的既有地铁隧道变形与应力数值,确定盾构施工具体参数,并根据施工监测数据总结盾构掘进参数等控制措施,保证下穿施工顺利实施。
Aiming at a subway project section underpassing the existing Subway Line 7 section, this paper analyzes the deformation and stress value of the existing subway tunnel caused by the construction in progress, determines the specific parameters of the shield construction, and summarizes the control measures such as shield tunneling parameters according to the construction monitoring data to ensure the smooth implementation of the underpass construction.
