探地雷达在隐伏岩溶区工程地质勘探中的应用

THE APPLICATION OF GROUND PENETRATING RADAR IN DETECTING UNDERGROUND KARST AN EXAMPLE FROM POSITIONTING GAOTANYUANPANLING

在简要介绍探地雷达工作原理、方法及雷达图象资料处理、解释等基础上，以广东增城高滩圆盘岭桥基选址探地雷达技术的应用为例，剖析了隐伏岩溶的雷达时间剖面中岩溶的反射波形组特征。在场地钻勘验证的基础上。

This paper gives a brief introduction to the principles and methods of ground penetrating radar, and to radar data processing by its application in engineering geophysical exploration for selecting Gaotanyuanpanling bridge site. The characteristics of the radar reflected wave of underground karst in radar time section are shown in this paper. Based on the drilling exploration in the site, a model between underground karst and radar reflected wave has been established and the engineering geology data for selecting the Gaotanyuanpanling bridge site is provided.
