摘　　要：近年来,BIM技术在交通运输基础工程领域的应用日益广泛,如地铁、高铁、公路、隧道等项目全生命周期的管理都有BIM技术的参与。本研究通过BIM软件–Revit建立浅埋隧道的信息模型,基于BIM信息模型,导入ABAQUS有限元分析软件,对越秀公园站浅埋暗挖多孔隧道进行有限元与无限元耦合模拟,验证了无限元在隧道数值模拟中的可行性。其次通过设置不同的工况,验证了无限元与有限元耦合模拟的准确性,并且研究了隧道的开挖对不同工况下,地表沉降和衬砌内力的影响,得出最优的开挖工序,为后续浅埋隧道的力学行为的研究提供借鉴。In recent years,BIM technology has been increasingly widely used in the field of transportation infrastructure engineering,such as subway,high-speed railway,highway,tunnel and other projects throughout the life cycle management,which are interspersed with BIM technology.In this application,the information model of shallow-buried tunnel is established through BIM software-Revit.Based on the BIM information model,the ABAQUS finite element analysis software is imported to conduct finite element and infinite element coupling simulation of shallow-buried and under-excavated porous tunnel at Yuexiu park station,The feasibility of infinite element in tunnel numerical simulation is verified.Secondly,the accuracy of coupling simulation of infinite element and finite element is verified by setting different working conditions,and the influence of tunnel excavation on surface settlement and lining internal force under different working conditions is studied,and the optimal excavation process is obtained,which provides reference for the follow-up study of mechanical behavior of shallow tunnels.
