摘要
大黑汀水库大坝主廊道于１９８８年发现在排水孔及排水沟内有大量的沉积物，分别为乳白色絮状物、黑色及红褐色物质。经对１７组排水孔及钻孔进行水质全分析，得出以下结论：在１５个坝段中，环境水对Ｆ１坝段、１４号坝段、１０号坝段、２０号坝段、２８号坝段护坦廊道存在中等程度的溶出性侵蚀。
Much deposition was found in the ditch of the main gallery of Daheiting Dam in 1988,including milky white,black and red brown precipitate. Through analysis of water quality for 17 groups of drainage holes and bore holes, several conclusions are drawn:at 15 sections,ambient water caused mediam corrosion to sections F 1,14,10 and 20 and the gallery of section 28.
