地质雷达技术在白云新城排渠堤围探测中的应用

Application of Geo-Radar Technology in Detection of Drainage Dykes and Embankments in Baiyun New City

河涌排渠堤围的保护是河长制工作的重要内容,查明河涌排渠堤围的脱空、空洞、填土密实情况以及填土含水率高低对堤围保护至关重要。地质雷达(GPR)是一个快速增长的领域,是已经看到有极大地进步中的发展中的理论,为堤围探测提供了一种方便快捷无损的探测技术手段。本文结合gprMax正演模拟图像分析了地质雷达在广州市白云新城排渠堤围探测中的应用,以期探索堤防的安全性及稳定性,根据检测结果,可以做出更有效的维护或修复决策。

The protection of river length drainage dike circumference is an important part of the work of river length drainage dike circumference.It is very important to check the empty,empty,fill density and fill water content of Hechung drainage levee circumference.Geological radar(GPR)is a rapidly growing field and a developing theory that has seen great progress,providing a convenient,fast and non-destructive detection technique for embankment detection.This paper introduces the application of gprMax in detecting the embankment of Baiyun New City,Guangzhou,in order to explore the safety and stability of the embankment,and make more effective maintenance or repair decisions according to the detection results.
