Application Of No-Destructive Inspection Technology In Hydraulic Engineering

The hydraulic engineering is the important infrastructure of the national economy and the social development. Because very many dikes its construction age remote either or raise year by year the flood immersion cultivate thick and so on the factors, often in the dike body inevitably has hidden dangers and so on cavity, crevasse, weak band, ant nest, affects the dike the security. The traditional embankment hidden danger survey method mainly is the artificial core testing and the mechanical drilling and so on, this kind of method survey both spends and is not comprehensive, comprehensively appraises the embankment quality with difficulty, and also has certain harm to embankment itself. Therefore, seeks the more scientific effective technical method, achieved fast surveys into in our country hydraulic engineering to the embankment hidden danger at present to urgently need the solution accurately an important issue.In view of this present situation, this article applies the lossless examination technology in the hydraulic engineering takes the research direction. First to current main lossless examination technology for example: The auspicious thunder surface wave law, the high density electrical method, searched the radar method, the temperature monitoring technology, the isotope monitor technology, the CT technology and so on have carried on the thorough understanding from the principle and the operating procedure, and analyzed the comparison, from fast, economical, the effective angle embarked, the choice high density resistivity method and searched the radar method to apply in the hydraulic engineering takes the research content.The high density resistivity method application including the dike soil texture distribution survey and the dam leakage channel survey, the union project example elaborates its application effect, and to its serviceable, the survey precision as well as the soil texture judgment aspect has carried on the discussion.The application of Ground Penetrating Radar technology include five aspects, namely the geological lamination test, the underground cavity shape goal body test, the subsoil water level line and the dam line of saturation test, the truncation infiltrate the body shape and the complete test and the derivation tunnel lining work quality examination. To its profile characteristic, the electromagnetism wave velocity of the earth medium, the water, the concrete has given induction showing.
