隧道在施工过程中常常出现严重的地质灾害,例如塌方、涌水、突泥和岩爆等。为了将地质灾害影响程度降到最低,施工前进行超前地质预报是十分必要的。文章介绍了TSP超前地质预报系统的技术特点和基本原理在铜锣山隧道现场的应用情况,预报结果显示,TSP法结合工程地质调查进行地质超前预报对隧道的安全施工具有积极的意义。
Tunnels often show serious geological disasters during construction, such as landslides, gushing water, mud and rock burst. In order to minimize the impact of geological disasters, it is necessary to carry out advanced geological forecasting before construction. The paper introduces the application of TSP advanced geologic forecasting system and the basic principle in the tunnel of Tongluo Mountain. The forecast results show that the TSP method is of great significance to the safe construction of the tunnel in combination with the engineering geological survey.
