介绍了TSP203隧道超前地质预报系统的基本原理、技术状况和在隧道隧洞尤其是隧道涌水段超前预报中的应用效果和达到的技术指标,并应用TSP203对重庆铁峰山公路隧道涌水坍塌段进行了的综合分析,其预报结果经验证与实际围岩开挖情况基本吻合,对类似工程有一定的指导意义。
This paper introduces the basic principle and technical condition of TSP203 advanced geological forecasting system and its application effect and technical index in advance prediction of tunnel tunnel, especially in tunnel gushing water section. TSP203 is applied to the gushing water collapse section of Tiefengshan highway tunnel in Chongqing Comprehensive analysis shows that its prediction results are basically consistent with the actual excavation of surrounding rock and have some guiding significance for similar projects.
