道路空洞无损探测技术发展研究

Research on the Development of Road Cavity non-destructive Detection Technology

我国道路建设逐渐向"由建转养"模式发展,随着道路空洞等病害的增加,道路空洞无损探测技术也迅速发展起来。道路空洞探测范围广、难度大,传统方法不能满足当前社会发展的要求。文章主要介绍了GPR和面波仪在道路空洞探测方面的发展和应用现状,提出了目前仪器探测存在的问题,针对目前的问题指出了未来无损探测技术的发展方向。

Road construction in China has gradually developed from construction to maintenance.With the increase of roads cavity and other defects,the non-destructive detection technology of roads has also developed rapidly.Road cavity needs to be detected in a wide range which is difficult to be realized,and traditional methods cannot meet the requirements of current social development.In this paper the working principle and application status of ground penetrating radar and surface wave instrument in road cavity detection are mainly introduced,and the problems existing in instrument detection are put forward.The development directions of the non-destructive detection technology are pointed out.
