基于地质雷达法的城市道路地下病害探测及实例应用

Underground Disease Detection of Urban Roads based on GPR and Its Application

文章基于地质雷达探测原理,研究分析了地质雷达的理论探测精度、现场测试和布线方法,针对疏松、富水、脱空和空洞等典型道路地下病害进行了地质雷达图谱分析。并对地质雷达干扰源进行了明确和细化,给出了部分典型干扰源的地质雷达图谱。同时,文章还以某道路的地质雷达探测工作为例,讨论分析了该段道路的主要病害形式及其形成原因,给出了针对性的处理建议。

Based on the detection principle of GPR, this paper studies and analyzes the theoretical detection accuracy, on-site testing and wiring methods of GPR, and analyzes the GPR atlas of typical road underground diseases such as looseness, rich water, void and cavity. In addition, the interference sources of GPR are clarified and refined, and the GPR atlas of some typical interference sources is given. At the same time, taking the GPR detection work of a road as an example, this paper discusses and analyzes the main disease forms and causes of this section of the road, and gives targeted treatment suggestions.
