摘要
从公路存在的常见缺陷出发,介绍了地质雷达探测的基本原理以及地质雷达检测路面的地球物理前提条件,就地质雷达在公路无损检测领域开展了较深入的探讨,以正常道路与病害道路为对比,系统分析了公路密实不均匀、局部脱空、裂隙、塌陷的原因,总结了常见缺陷的雷达波相特征,针对不同的异常做了详细的解释,为公路检测及治理提供一定科学依据。
This paper,from the perspective of common road defects,introduces the basic principles of the geological radar detection and the geological geophysical condition of the geological radar detection road,and makes a further discussion on the application of the geological radar to the non-destructive testing.Comparing the normal road with poor road,it analyzes the reasons about the unevenness of the road density,the fault,the collapse and so on.Finally it concludes the characteristics of the common defects of radar facies.
