Abstract: The paper introduced the probing method of Ground Penetrating Radar (GPR) and discussed the application of high frequency Ground Penetrating Radar (GPR) into concrete cracks probing on the crest of clay core wall rockfill dam. By use of GPR, the character and cause of concrete cracks on the crest can be probed rapidly and non- destructively.
