地质雷达探测道路病害的案例分析与思考

Case analysis and thinking of detecting road diseases by ground penetrating radar

道路是城市发展的动脉,承载着交通运输、城市服务等重要功能,道路安全一直是城市安全的重要组成部分。道路病害具有隐伏性、突发性、多因素等特点,如何快速、有效地找到道路病害就显得尤为重要。通过选取典型案例,从地质雷达的原理、测区环境、地下构筑物的关系等方面分析总结了三维和二维地质雷达系统探测道路病害的过程。尤其是新建不久的道路存在病害就值得我们仔细分析其中的原因,探讨雷达检测是否应作为道路检验、验收的一部分。

In recent years,road collapse and other diseases have occurred frequently,especially in the rainy season,with a higher frequency.In particular,cavity disease has become one of the crucial disasters in cities.In recent years,finding the diseased body quickly and effectively has become an urgent problem to solve.Road diseases have the characteristics of concealment,outbursts,and multifactorial.Urban roads have high population density,large traffic flow,and complex underground structures.These factors make it challenging to find and lock down underground diseases.Select typical cases,analyze and summarize the process of three-dimensional and two-dimensional geological radar systems detecting underground diseases after the completion of urban road projects from the aspects of the principle of geological radar,the environment of the survey area,and the relationship between underground structures.Especially for newly built roads,the existence of disease bodies is worth careful analysis of the reasons and whether radar detection should be a part of road inspection and acceptance.
