摘要
在相对固定过水土石坝（围堰）下游混凝土板护坡垫层厚度的基础上，通过试验分析了不同渗透性垫层料降低混凝土护板下渗透压力的效果；同时，也探讨了这些垫层料的一些力学性质。最后提出了满足最佳减压效果的垫层料设计准则。
On the basis of relative fixed cushion layer depth of concrete slab slope protection downstream of overtapped embankment dam(cofferdam),the effect of reducing seepage pressure under concrete guard board by cushion layer materials with different permeability is analysed through tests;at the same time,some mechanical properties of cushion layer are investigated.Finally,the cushion layer design criterion satisfying the best pressure reducing effect is presented.
