摘　　要：隧洞工程在交通、水利项目建设中极为常见,而TBM是最先进的隧洞掘进技术。本文以新疆SS隧洞Ⅱ标段工程为例,根据工程实际设计了施工方案和TBM机类型,并分析了工程所应用的超前地质预报技术,包括TSP法和超前钻法,阐述了在软弱破碎带和地下水含量较高地段的具体处理措施,可为类似工程提供必要的技术参考。Tunnel project is very common in the construction of transportation and water conservancy projects,and TBM is the most advanced tunnel tunneling technology.Based on the SS tunnel bidⅡproject in Xinjiang as an example,according to the actual engineering design construction plan and the TBM machine types,and analyzes the application of advanced geological forecast technology in project,including TSP method and advanced drilling method.The specific treatment measures in the soft crushing zone and the area with high groundwater content are described,which can provide necessary technical reference for similar projects.
