根据过水土石坝（围堰）下游混凝土板护坡垫层可能受水流向上渗和向下渗的交替作用，以及自身结构的特点（如不均匀系数很大等），对垫层料进行了渗透稳定分析并提出防止渗透破坏的反滤设计准则。
According to the alternation effect of infiltration and down infiltration of the concrete slab downstream of the over-flow earth dam (cofferdam), as well as the characteristics of its own structure (such as large nonuniformity coefficient), the cushion material is infiltrated Stable analysis and propose to prevent infiltration destruction of the filter design criteria.
