综合探测技术在堤坝渗漏隐患调查中的应用

堤坝的安全运行关系到国民经济建设和人民生命财产安全,重要性无容置疑.结合多年堤坝渗漏隐患调查的实践经验,分析高密度电法、自然电场法、原位试验和室内土工试验等探测技术的优缺点,即采用高密度电法探测渗漏异常区的空间分布,采用自然电场法探测是否存在渗漏通道,原位试验和室内土工试验则对上述异常进行验证,并结合堤坝隐患的性质进行具体分析和判断,总结出一套行之有效的堤坝渗漏隐患综合探测方法,为后期加固除险提供依据.

Application of Comprehensive Detection Technique in Investigation of Dam with Leakage Hidden Trouble

The safe operation of the dams relationship to the national economic construction and people＇s lives and property safety, the importance undoubtedly. This article practical experience combined with years of dam leakage hazards survey, analysis of the advanta- ges and disadvantages of high density electrical, natural electric field, in - situ testing and indoor soil test detection technology, used high density electrical detecting Spatial distribution for Leakage anomaly, natural electric field detecting Leakage channel, and in - situ testing and indoor soil test verified these abnormalities, Combined with the specific nature of the dam hazard analysis and judgment, summed up a set of effective detection method of dam leakage risks, provided the basis for post - reinforcement Danger.
