地质雷达在犇溪口隧道超前地质预报中的应用

Application of ground penetrating radar in Benxikou tunnel geological prediction

介绍了地质雷达进行超前地质预报的工作原理.以地质雷达在水绥二级公路犇溪口隧道施工中的应用为例,通过对地质雷达图像的解析进行了超前地质预报.实践证明地质雷达是隧道施工超前地质预报的一种快捷有效的方法,对隧道施工具有较好的指导作用.

The working principle of ground penetrating radar （GPR） for geological forecast was introduced. In the ease of the application of GPR in Benxikou tunnel of Shui-Sui secondary road, a geological forecast was conducted according to the geological radar image. It shows that geological radar is a quick and efficient way for geological forecast during the construction of the tunnel,and can provide a good guide for tunnel construction.
