Non damage detecting holes of dam''s plate by comprehensive Geophysical Prospecting
采用综合物探法进行大坝面板脱空无损探测

At present non-damage detecting holes of dam's plate is still a different subject.There is no successful report about this subject.The results obtained only by Geophysical prospecting have low accuracy.Therefore how to raise accuracy of detecting holes of dam's plate is an urgent problem.The authors use comprehensive geophysical prospecting method to detect holes of dam's plate for hydro-station of Tian-sheng Bridge and obtain a very successful result.In this prospecting a better economical benefit is also gained.
