摘　　要：探地雷达作为一种高精度无损探测新技术,已广泛应用于工程勘察各领域,具有探测速度快、定位准确、轻便灵活、可实现连续透视扫描以及二维彩色图像实时显示等优点。不同的地质条件,探地雷达将表现为不同的波谱特征。文章在分析了探地雷达的分辨率与地层介质、探测深度、天线频率的基础上,例举了其在第四系地质、活动断裂、滑坡、土体性质等不同地质条件下的探测效果。Underground detecting radar as a h igh precision and nondestructive inspection new technology,has extensively used in various domain of prospecting.It has strong points of high-speed,accurate locating,portable and easy to handle,continuous per-spective scanning and tw o dimensional color image real-time display and so on.For different geologi cal condition,the under-ground detecting radar will show different spectrum c haracteristics.On the basis of the radar's resolution and stratigraphic medi-u m,investigating depth,antenna frequency analyses,the paper illustrates with e xamples of prospecting effects under different geo-logical conditions of Quate rnary strata,active faults,landslides,soil mass and so on.
