摘　　要：主要介绍TSP超前地质预报基本原理和现场工作以及现状、问题。为进一步查明隧道施工前期未知的、潜藏的一些地质问题,采用TSP超前地质预报,指导隧道施工。从洞内现场地质调查、TSP野外数据采集、数据处理、TSP探测成果及分析等几个方面阐述了TSP超前地质预报在某隧道中的应用,同时介绍其预报结果。TSP超前地质预报法可准确地预判掌子面前方某一段落的地质情况——岩体的破碎程度、地下水发育及岩溶发育。为隧道施工提供重要信息,减少了隧道施工过程中地质灾害的发生和危害,能确保隧道施工的安全。The paper mainly introduces the basic principle of TSP geological forecast and field work as well as the current situation and problems. In order to further find out the unknown and potential geological problems in the early stage of tunnel construction, the TSP geological forecast is used to guide the construction of the tunnel. From the field geological investigation, TSP field data collection, data processing, results of the TSP detection and analysis, the paper introduces the application of TSP geological forecast in Xiaoshan mountain tunnel, and gives the forecast results. The TSP geological forecast method can accurately predict geological conditions of rock mass in front of the tunnel facecrushing degree of rock mass, groundwater and karst development. TSP geological forecast has provided important information for tunnel information construction, reduced the occurrence of geological hazards in the process of tunnel construction and ensure the safety of the tunnel construction.
