摘要
探讨了利用地质雷达技术进行岩溶裂隙水探测的技术方法,结合雷达探测远离分析了岩溶裂隙水的探测可能性。基于电磁波传播理论,研究了电磁波在含水构造界面上的反射能量分配规律。最后结合工程实例,对地质雷达数据进行了处理,并对岩溶裂隙水进行了综合判断。与开挖结果对比显示,应用地质雷达可较大地提高岩溶裂隙水预报的准确性和可信性。
This paper discusses the technical details of detection the groundwater in the highly developed karst rocks using Ground Penetrating Radar (GPR). The feasibility of this technique is also discussed in the paper based on the principles of the GPR. The deflected energy at the groundwater-rock interface is quantitatively analyzed based on the electro--magnetic wave propagation theory. The paper also demonstrates the GPR data processing technique in the groundwater detection using a case history. The GPR predicted results are compared with the site excavations and found that the GPR technique improves the accuracy as well as the reliability of the groundwater prediction.
