摘　　要：本文介绍了探地雷达的工作原理,对射频天线的参数选择,数据处理时干扰信息的认定及消除,最终反演结果的分析等内容。以河北秦皇岛经济技术开发区区域地震安全性评价项目中对构造、第四系界面的划分为实例,通过面波勘探、地震映射与探地雷达方法试验结果的对比,探讨探地雷达在地震安全性评价划分岩性界面中的应用效果。经钻孔验证,探测结果与实际较吻合,表明该方法适用于此类地层划分工作。This paper introduces the working principle of GPR,the parameter selection of RF antenna,the identification and elimination of interference information during data processing,and the analysis of final inversion results.Taking the division of tectonic and quaternary interfaces in the regional seismic safety assessment project of Qinhuangdao Economic and Technological Development Zone in Hebei province as an example,the application effect of ground penetrating radar(GPR)in the division of lithologic interfaces in seismic safety assessment is discussed by comparing the results of surface wave exploration,seismic mapping and GPR test.Drilling verification shows that the detection results are in good agreement with the practice,indicating that the method is sui-table for this kind of stratigraphic division work.
