小浪底大坝两岸坝肩山体渗漏特性分析与处理措施

Analysis and Treatment of Dam-shoulder Mountain Seepage Characteristic for Xiaolangdi Project

小浪底大坝两岸坝肩山体存在透(含)水岩层和相对隔水岩层交替层状分布、倾向下游、断裂构造发育、上部风化卸荷严重等特点,水库蓄水后两岸坝肩山体出现层状渗漏、带状渗漏和壳状渗漏的特性,针对渗漏采取了防渗处理措施,取得了明显效果。

In the dam-shoulder mountain of Xiaolangdi project, there are the characteristics of the interphase of the dank terriain and the insulation terrain,leaning to the downstream, the growth of the rupture configuration and the severity of the wathering unloading. After the impounding of the reservoir, the characteristic of the layer seepage the zonal seepage and the shell seepage became obvious. According to the seepage characteristic, the strengthening measures have been taken. The effect is very prominent.
