摘要
本文介绍了目前国内外探地雷达系统的产品公司和应用范围,又以湖南某隧道地质勘察为例,介绍了探地雷达的工作原理及数据解释分析,表明探地雷达对勘察隧道及周边的地质情况、断层破碎带、涌水、软弱围岩等不良地质现象具有较好的效果,为隧道开挖提供了可靠的地质资料,节约了施工成本,保障了隧道的施工安全。
This paper introduces the product companies and application scope of ground penetrating radar system at home and abroad at present, and takes the geological survey of a tunnel in Hunan Prov-ince as an example, introduces the working principle and data interpretation and analysis of GPR, which shows that GPR has a good effect on the geological survey of the tunnel and its surrounding areas, fault fracture zone, water gusher, weak surrounding rock and other bad geological phe-nomena, provides reliable geological data for tunnel excavation, saves construction cost and guarantees the construction safety of the tunnel.
