摘要
湘西地区工程地质条件复杂,对高速公路施工及运营安全构成极大的潜在威胁。在对其进行岩溶勘察的过程中,传统的钻探方法存在周期长、成本高、场地受限等缺陷。主要探讨综合地球物理勘探方法在湘西张家界～花垣高速公路勘察过程中的应用效果。实践证明,工程物探方法可以弥补钻探以点代面的不足,并在湘西地区岩溶勘察中取得了良好的效果,为探讨湘西岩溶发育规律及后期的道路岩溶探测提供经验参考。
The geological conditions are complex in the west of Hunan Province.It is a great potential threat to construction and operation of highways.The drilling,a traditional method,has a lot of defects,such as longer cycle,higher cost,limited by space in karsts investigation.In this paper,the application effects of integrated geophysical exploration methods to explore karsts of Zhangjiajie-Huayuan Expressway in the western of Hunan Province are mainly discussed.According to the results,the engineering geophysical methods can make up the defects of drilling,and achieve good results in karsts survey.All of those can provide a reference for karsts exploration in the western of Hunan Province.
