综合物探方法在哈达山防渗墙检测中的应用

Application of integrated geophysical prospection of anti-seepage wall of Hadashan hydro project

防渗墙检测有很多方法,跨孔声波检测作为常规有效的检测手段一直被业界沿用至今,而高密度电法检测防渗墙的均匀性是近几年在水电站才得到较多实际应用,实践证明,该方法有明显、直观及无损等优点,结合跨孔声波检测能直接反应混凝土分布的真实情况。

There are many ways to detect anti-seepage walls, and the detection of the cross holes acoustic wave is still a routine and effective detection mean until now. The high density resistivity method with the detection uniformity has got the more practical application in the hydropower station in recent years. The practice has proved that this method has the obvious advantages of the clear, intuitive as well as nondestructive, reflects directly the real situation of the concrete distribution combining with the detection of cross holes acoustic wave.
