摘　　要：隧道施工特别是复杂地质条件下的施工面临着很多地质灾害问题,如岩溶地段的突水突泥、断层破碎带的塌方等,为了避免这些灾害事故的发生,开挖前必须对掌子面前方的地质条件有一个较好的了解,以采取必要的防范措施。文章介绍了目前公路隧道中常用的超前地质预报方法,论述了各种方法的原理、优缺点和适用条件,在技术现状分析的基础上,讨论了综合超前地质预报的必要性,并提出了高风险隧道的综合超前预报技术体系,探讨了今后超前地质预报的发展方向。Geological hazard accidents often occur in the course of tunnel constructions, especially in the condition of complex geology, such as the water and mud rush in karst region and the landslip of the faulted zone. In order to avoid such accidents, a better understand of rock mass in front of working face must be done before the excavation, so the countermeasure can be prepared beforehand. In this paper, several advanced geological prediction technologies are introduced including.TSP, geological radar and infrared water detecting method , their merits and demerits and application condition are also discussed. The necessity and technical system of comprehensive geological forecast are discussed. In the end, the henceforth development direction are proposed.
