摘要
结合南京某越江地铁区间盾构隧道工程实例,采用大型有限元软件ANSYS进行地铁盾构隧道掘进施工过程三维仿真分析,在此基础上,就盾构隧道掘进施工引起的地层位移、地表沉隆和管片衬砌结构的内力3个方面进行了分析,为地铁区间盾构隧道施工及监控量测提供了参考.
Based on the shield tunnel engineering of the cross-river Nanjing subway, using large-scale finite element software ANSYS, the shield tunneling construction process is simulated. The strata displacement, surface sink and internal force of segment lining structure caused by shield tunneling construction are analyzed, which provides reference for the subway shield tunnel construction and the inspection measurement.
