Detection of Seepage Path of Dam Foundation Based on Groundvue Radar

Location of Nanmenxia Reservoir is very important, and the reservoir has a significant benefit. But the leakage of dam foundation was serious; there was an urgent need to find out leakage location and path. The effect of previous treatment was not obvious, and it is very important to find out the situation of the dam foundation. Through the introduction of British Groundvue series of Ground Penetrating Radar System, the seepage channel was detected, and main leakage paths of dam foundation were looked for. By detecting and analysis, drawed a conclusion that there was obvious strong leakage band in the bedrock, the local obviously broken belt developed on the right bank of the grouting trnnel. It provided technical support for design and construction of danger removal and reinforcement for Nanmenxia Reservoir.
