采用综合物探法进行大坝面板脱空无损探测

Non-damage detecting holes of dam's plate by comprehensive Geophysical Prospecting

面板堆石坝大坝面板脱空无损探测目前仍是一个难题,尚未见到较为成功的探测报道,采用的单一物探方法的探测成果准确率又偏低.因此,如何提高探测准确率是面板脱空无损探测的研究重点.本文通过天生桥一级水电站面板脱空探测的实例,介绍采用综合物探方法进行大坝脱空探测是可行的,并在实践中获得成功,取得了较好的经济效益.

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.
