摘要
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呈现出层状渗漏、带状渗漏和壳状渗漏的特性,针对渗漏特性采取了防渗处理措施,取得了明显效果。
The dam abutment mountain mass on both banks of the Xiaolangdi Water Control Project is characterized by an alternate distribution of permeable layer,water-carrying layer and relative water barrier layer,dipping downstream,with fractured tectonic development and serious unloading via upper weathering.After impoundment of the reservoir,the dam abutment mountain mass on both banks has featured with the sandwich permeation,strip permeation and shell permeation.The anti-seepage treatment measures are applied according to the permeability features,resulting in an outstanding effect.
