摘要
岩溶地区隧道工程经常遇到溶洞、突水、突泥、坍塌等地质灾害的威胁,因此,在施工时辅以地质预报是十分必要的。通过研究地质分析法、地质雷达、弹性波反射法(以TSP为例)等超前地质预报技术在某高速公路隧道中岩溶预报的应用,提出针对岩溶地质条件的施工建议,并对照实际开挖情况,分析了由多种预报手段综合而成的预报系统的实用性以及在指导施工方面的重要作用。
Because of the frequent encountering of serious geo-hazards such as karst caves,water inrush,brush mud and collapse,geological prediction is rather essential in the construction.Through analyzing geological prediction methods which is applied tunnel karst prediction about an expressway,these methods including the geological method,GPR(ground penetrating radar)and seismic wave reflection method(focus on TSP) etc,the suggestions for construction are put forward to the geological condition of karst,at last,we analyze the practicability and the importance of the prediction system including the methods above mentioned in accordance in the excavation situation.
