地质雷达在公路隧道超前地质预报中方法探讨

A Method of Round Penetrating Radar to Geological Forecast for Expressway Tunnel

近年来地质雷达在公路隧道超前地质预报工作中被广泛采用,它能发现掌子面前方地层的变化,对于断裂带特别是含水带、破碎带有较高的识别能力。结合瑞典RAMAC CU型地质雷达的应用实例,介绍地质雷达的工作原理及其在龙阁岭隧道超前地质预报中的具体应用。

In recent years, Ground Penetrating Radar is widely used in the geological prediction of expressway tunnels. It can find out the formation change in front of the work face and has high recognition ability to the fracture zone, particularly the aquifer zone and the crushing zone. In this paper, the principle of geological radar and its application in expressway Tunnel geolog- ical prediction is introduced with a application example of the Sweden RAMAC CUII geological radar.
