四川省某水库坝后浸润区成因分析

Research on Seepage Area of Certain Reservoir in Sichuan

四川省某水库自建成蓄水以来,在大坝下游左岸坡面一直存在着散浸现象,但对于坝后浸润区的成因却不能确定。浸润区的存在表明坝体内水位较高,对边坡的稳定性有不利影响。究明其范围、成因、补给水源对于坝体的安全性评价有着非常重要的意义。现通过多种手段,结合大坝观测资料,分析其可能的成因。

Since the impounding of certain reservoir in Sichuan Province, there are separate seepage areas at the downstream slope surface. But the reason of seepage is still uncertain. Seepage means that the water level in dam is too high and it is harm to slope stability. It is very important to ensure the cause of seepage for safety evaluation of dam. The reason of seepage by all kinds of methods is shown.
