Application of Ground Penetrating Radar in Reservoir Leakage Detection in Complex Geological Areas

Abstract

As a typical nondestructive testing method, ground penetrating radar (GPR) has been widely applied in geological detections of highways and coalmines, but rarely in leakage detection of reservoirs. Taking Taohe Reservoir as an example, this paper deploys multiple GPR detection lines on site, and carries out intensive detection in the upstream/downstream of the reservoir, as well as on the left/right abutments of the dam. In this way, leaks were detected on the left and right dam abutments. The detection results provide a reference for subsequent analysis and treatment of reservoir leakage.

Direct Coupled Wave Removal for GPR Data Based on SVD in the Wavelet Domain

“…Ground penetrating radar (GPR) is a geophysical exploration method that uses high frequency (1 MHz-10 GHz) electromagnetic waves to non-destructively detect invisible targets in the ground. With the advantages of simple operation, high resolution, and strong anti-interference capability, the GPR technology has been widely used in tunnel lining detection [1], [2], geological surveys [3], pipeline detection [4], [5], and many other fields. In the process of exploration, in order to maintain more reflected wave characteristics of targets, the GPR generally uses broadband to record.…”
