摘　　要：以ASTM标准规范为基础对探地雷达(Ground Penetrating Radar以下简称GPR)的地下探测方法的应用做了比较系统的概述,主要内容包括:部分专业术语的解释;测试过程中雷达探测深度及其中心频率、垂直分辨率、水平分辨率等的关系,测试过程中常见的天线移动方式,以及雷达波速的预测几种方法,数据显示方式;雷达数据解释和数据处理的一般过程及方法.目前我国尚没有关于GPR的国家规范或行业标准,文章对GPR的使用及规范的编制具有一定的参考意义.The method of sarface ground penetrating radar （GPR） applied in subsurface investigattion are systemic summarized based on ASTM standard guide. It indudes the oart terminology; the relationship between penetration depth of radar and central frequency, vertical resolution and lateral resolution; the selection of approach in the field procedures; the methool for estimating propagation velocity and velocity sounding; data display and inter pretation methodsfor the assessment of subsurface materials. An overview of the impulse GPR methad is prouided in the paper and GPR measurements as described in the paper are used in geologic, engineering, hydrologic and envirmental application. Since up to now, there isn＇t any national or vocational standard guide on GPR, the paper can be reference for GPR application and preparation for GPR guode.
