摘　　要：某特定场址区域的地下工程采用敞开式隧道掘进机(TBM)进行斜坡道施工,在掘进过程中,如果遭遇断层破碎带,将严重影响现场安全和掘进效率,为此亟须建立一套适合的支护体系来满足现场施工及后续作业需求。基于工程现状,确定TBM快速通过断层破碎带时的支护材料和小型支护设备,形成适用于现场的支护体系,可为类似工程提供参考。In the underground engineering of a specific site area,an open tunnel boring machine(TBM)was used for slope construction.In the process of excavation,if the fault fracture zone is encountered,the site safety and excavation efficiency will be seriously affected.Therefore,it is urgent to establish a suitable support system to meet the on-site and subsequent needs.The supporting materials and small supporting equipment for the rapid passage of TBM through the fault fracture zone are determined through the comparative analysis of field tests,and the supporting system suitable for the site is formed,in order to provide reference for the construction of similar projects.
