MALA探地雷达在地下管线探测中的应用研究

Application of Ground-penetrating Radar MALA in Underground Pipeline Exploration

通过研究不同材质、管径的地下管线的雷达图成像规律,利用地下管线探测生产项目进行了研究验证,选取钢管、玻璃、砼、塑料等不同材质的地下管线进行雷达探测实验,验证不同管线材质的雷达探测成像规律。然后在材质相同的条件下选取管径不同的地下管线进行探测分析,通过影像变化规律辅助判断识别管径大小,同时实现了典型的管径大小计算,并进行现场实际验证。

In this article,we veri ed the radar mapping imaging rules with di erent underground piping materials in the underground pipeline detection production project with di erent materials and diameters by studying,including steel pipe,glass,concrete and plastic. en with the material under a same condition,we selected the underground pipelines with different diameters for detection and analysis,and determined and recognized the size of pipe diameter with the aid of image change rules.Meanwhile,we calculated the diameter size of typical pipelines and veri ed it in eld.
