地质雷达在给水管线探测中的新进展

New Progress of GPR to Detect Water Supply Line

在引进意大利RIS-K2型地质雷达后,该院在给水管线探测方面取得了较大的进展。一般情况下,近距离的多根金属管线,采用管线仪探测难以分辨,而采用地质雷达探测能有效分开;通过雷达图象特征分析,可以进行管线的材质分辨;利用雷达反射波的多次波间距,可以计算非金属给水管的管径。

The detection of water supply line has a great progress since the introduction of RIS-K2 GPR made in Italy in our institute. Generally speaking, many close distance metal pipelines can＇t be distinguished by the pipeline detectors, but can be easily distinguished by GPR; Through analyzing radar images, we can distinguish the material of the detected pipes;and also calculate the diameters of non-metallic water supply pipes by the spacing of multiple waves interval of radar reflected wave.
