地质雷达在土层疏松和空洞探测中的应用

本文在简述地质雷达基本原理及工作方法的基础上，阐述了地质雷达的信号识别在土层疏松及空洞探测中的可行性及准确性，并对地质雷达的实测资料进行了处理及分析。结果表明，地质雷达检测技术能有效的探测土层疏松以及空洞异常，从而避免地铁施工过程中地下空洞等地质体对周围环境和施工安全造成的不良影响。

In this paper, on the base of depicting basic theory and work method of ground penetrating radar, the feasibility and veraeity of GPR signals recognition were expatiated in this respect of detecting loosening soil layer and hole, then the actually measurable data of GPR were processed and analyzed. The results showed that the distributing of loosening soil layer and hole were effectively estimated by the GPR technology, thereby the bad effect of loosening soil layer and hole will be avoided for underground construction.
