地质雷达在隧道塌方空腔探测中的应用

Application of Ground Penetrating Radar to cavity detecting for tunnel's collapse

基于地质雷达的工作原理,讨论了探测隧道塌方空腔的理论和方法,并阐述了使用地质雷达系统对浙江省某两条高速公路隧道进行塌方空腔探测的情况,最终表明地质雷达法可应用于隧道塌方空腔规模的预估。

Based on the working principle of Ground Penetrating Radar, the theory and the method of cavity detecting for tunnel＇s collapse are discussed, besides, the condition of using GPR to detect cavity caused by collapse is described, finally, the results show that by using the Ground Penetrating Radar, the dimensions of tunnel＇ s collapse can be estimated.
