地质雷达在地铁施工前期道路探测中的应用

The Application of Geological Radar in Road Detection in the Early Stage of Subway Construction

在地铁施工前期,对地下病害体的探测尤为重要,文章从简要介绍地质雷达法的工作原理出发,通过结合工程实例,分析了不同地下介质异常体所产生的地质雷达图像特征,并对其中的探测剖面进行钻探验证,说明地质雷达在地铁施工前期在地下病害体探测中的效果。最后根据工程实践,给出地质雷达在地下病害体探测过程中应注意的问题,为类似工程施工提供借鉴和参考。

In the early stage of subway construction,the detection of underground diseases is particularly important.This article starts from a brief introduction to the working principle of the geological radar method,and combines engineering examples to analyze the characteristics of geological radar images generated by different underground media The detection profile is drilled to verify the effectiveness of the ground penetrating radar in the detection of underground diseases in the early stage of subway construction.Finally,according to engineering practice,the problems that should be paid attention to in the detection of underground disease bodies by ground penetrating radar are given to provide reference for the construction of similar projects.
