Application of Ground Penetrating Radar in Dam Body Detection

Abstract The basic principle, the detection methods, data processing, interpretation method and the application of ground penetrating radar in the dam body detection were introduced and the problems aroused during application were primarily studied. The cause of the dam leakage was very complicated and through geophysical prospecting the reasons for the dam leakage and relevant reinforcement measures can be provided. The leakage parts will appear to be electromagnetic abnormal due to the changes of the water content, which will be an advantage in the application of geological radar method. The dam body was detected using Ground penetrating radar detection technology and the quality of the dam project were analyzed combining with geological conditions, practical situation of the project and the characteristics of the radar images. The location of the crack fracture zone in the dam was predicted and feasible technological measures were put forward.
