探地雷达在福州某路面塌陷勘察中的应用

Application of GPR in the investigation of subsided road in Fuzhou

探地雷达因其快捷、经济的特点,在现今城市道路勘察中得到了广泛的应用。结合对福州某路面塌陷的勘察实例,介绍了探地雷达剖面法的工作方式及其原理,在该工程得到的雷达剖面上认清了路面下方的管线和地层的分布情况,从而对塌陷区域周边是否还会继续塌陷进行了评价。

Nowadays, Ground Penetrating Radar （GPR） has been widely applied in the investigation of roads in cities, for its characteris- tics of fast and economy. Based on the example of investigation of subsided road in Fuzhou, profiling work mode and principle of GPR is introduced. Through the profiles of GPR, we get clear understanding of line pipes and formation below the surface, in order to evaluate the collapse possibility around the collapse region.
