摘要
总结了探地雷达探测的技术工作方法,讨论了强干扰背景下的数据处理过程,列举了探地雷达低频天线在岩性界面划分、软弱地质体圈定、活动断层探测、地裂缝探测、抛石界线划分等方面的应用实例。实践表明,要获得高分辨率的探地雷达探测剖面,资料收集、现场踏勘、干扰因素分析、数据采集过程和数据处理流程的比选实验是非常重要的。希望通过本文的介绍和讨论,对使用探地雷达低频天线开展深层探测起到帮助和借鉴,更大地发挥探地雷达低频天线的探测能力与作用。
Based on the introduction of the principle of ground penetrating radar（ GPR） and the processing of contaminated data with strong background noise,this paper shows some case studies of GPR with low frequency antennas applied in identification of lithologic boundary and weak geological body,detection of active fault and fissure,and delineation of riprap interface. These cases show that in order to obtain GPR data with high resolution,it is important in information collection,field reconnaissance,interference factor analysis,data acquisition,and comparison of data processing flows. The discussion in this paper is helpful to the deeper exploration by GPR with low frequency antennas.
