电法测漏在垂直铺塑工程中的研究现状

我国现阶段存在大量有防渗问题的堤坝,垂直铺塑技术在大量工程实践中证明其相对于其他堤坝防渗措施具有适用范围广、防渗效果好、施工方便、经济性高等显著优点,具有极好的运用前景。双电极法及电极栅格法已经成功运用于垃圾填埋场,但因垂直铺塑方法的特点,这两种测漏方法难以直接运用于垂直铺塑的质量检测中。国内外现阶段垂直铺塑防渗膜的电学检测方法的研究处于起步阶段,仍没有在工程实际中大量运用电学测漏方法。

Research Status of Electrical Leakage Detection in Verti-cal Plastic Spreading Engineering

There are a large number of levees with seepage prevention problems in China at the present stage. It is proved in large amounts of engineering practice that the vertical plastic spreading technology, compared with other seepage prevention measures for levees, can be applied extensively and has a superb prospect for application, as it possesses several significant advantages such as good effect of seepage prevention, convenient construction,and high economy. Double electrode method and electrode grid method have been successfully applied to landfills, but due to the characteristics of vertical plastic spreading method, it is difficult for the two leakage detection methods to be directly applied to the quality inspection of vertical plastic spreading. At present, domestic and foreign studies on the electrical detection method based on vertical plastic spreading geomembranes are both at the initial stage, and electrical leakage detection methods have not yet been widely applied in practical engineering.
