| 摘 要： | “相对隔水层”这一术语在我国水文地质界已广泛使用。在碳酸盐岩层分布地区寻找微弱的岩溶化岩层作为相对隔水层,对大比例尺水电工程地质测绘是具有实际意义的。例如广西红水河流域,大面积分布着厚层石灰岩及白云岩,很少见到碎屑岩夹层;从而寻找相对隔水层对论证水库、坝址渗漏是有特殊意义的。但是,如何确定相对隔水层?这个问题尚未得到解决。

| Abstract: | The study of relative impermeable layer in carbonate rocks is of practical significance to determine the seepage of dam and water reservoir in karst areas. After a analysis of the combination of various rocks in karstificated formation, it is pointed out that the S (numbers of insoluble layers, in %), the T (ratio thickness of insoluble and easily soluble rocks) and the H (thickness of soluble single bed or intercalated beds) may be regarded as indexes for consideration of weak karatificated formation. On the basis of the data accumulated in practice the classification of relative impermeable layers is here also suggested. |
