摘    要：地质雷达方法是20世纪70年代发展起来的一种用于确定地下介质分布的广谱电磁法,它以经济、无损、快速而直观的特点成为浅部地球物理勘察最主要的工具之一.采用先进的地质雷达探测系统和高分辨雷达信息处理软件,可以探明路基深度20 m范围内下方古采矿洞的空间分布,探测深度比优于1/10.探测结果可为路基病害的处治和施工提供科学依据和必要的技术资料.

Abstract: The method of GPR is a wide spectrum electromagnetic method which can verify the distribution of underground mediums. This method was developed in the 1970′s. It has become one of the most important means of shallow depth geophysical surveying because of its characteristics———economical, non-destructive, quick and visible. Adopting the developed GPR instrument and high distinctive processing software of GPR data, the distribution of ancient mining cavities within the depth of 20 meters under the highway base can be prospected. The ratio of prospecting depth is better than 1/10. The prospecting results can supply scientific basis and necessary technical data for processing and renovating of faults in highway base.
