隧道工程中探地雷达空洞探测机理研究与应用

简要探讨了地质雷达无损探测空洞的机理，并在湖南某隧道运用地质雷达对衬砌和塌方区注浆回填体密实性进行检测。实际探测结果证明地质雷达探测法具有快速、精确定位空洞之优点，具有可以针对性实施钻孔回灌的巨大优势，从而为大型隧道工程开展高效无损检测以期大幅度提高其安全储备及质量等级提供了强有力手段，同时拓展了地质雷达在地球物理勘探学科中的应用领域。

Research on cavity detection mechanism of ground penetrating radar and its application

The paper explores the mechanism for the scatheless detection of cavity with ground penetrating radar, inspects the lining and refilled compactness of grouting at landslide areas by adopting the ground radar in some tunnel in Hu＇ nan, proves by the factual inspection results that the ground penetrating radar has the advantages of speedy and accurate location of the cavity with huge advantages of implementing the drilling re- circulation, so as to implement the effective scatheless detection in large-scale tunnel projects for providing the effective measures for improving its safety storage, and quality degrees and extending the ground radar＇ s application in the physical observation field.
