摘　　要：以某拟建地铁站出入口顶推箱涵下穿既有公路工程为研究背景,基于Midas GTS NX有限元分析软件开展数值模拟分析。综合考虑地质条件、施工阶段、公路及地下管网运营荷载等因素,模拟基坑开挖及顶推箱涵施工全过程,对穿越路段的路基沉降和地下管网位移的影响等进行分析,并提出相应的施工措施建议,确保施工质量及公路运营安全。Taking the incremental launching box culvert at the entrance and exit of a proposed metro station crossing the existing highway project as the research background,the numerical simulation analysis is carried out based on the Midas GTS NX finite element analysis software.Taking the factors such as geological condition,construction stage,and operational load of highways and underground pipe network and so on into account comprehensively,the entire process of foundation pit excavation and incremental launching box culvert construction is simulated,the impact of roadbed settlement and underground pipe network displacement on the crossing section is analyzed,and the corresponding construction measures and suggestions are put forward,so as to ensure the construction quality and highway operation safety.
