摘　　要：砂石反滤层是一种非常重要的工程结构,土石坝工程、竖式排水体、渗渠以及其它取水构筑物等水平与竖向水工结构都离不开反滤层,其质量甚为重要。本文根据反滤层“滤土”和“排水”功能,对反滤层的构造、设计方法等方面做了较系统的探讨。Sand/gravel anti-filter layer is a very important engineering structure. The horizontal or vertical hydro-structure such as earth rockfill dam, vertical displacement hull, seepage channel and other intake structures depend on it. So the quality of its structure is very important. Based on the anti-filter layer＇ s function of ＂filtering soil＂ and ＂abstraction of water＂, the structure of anti-falter layer, the design method and the research of filter criteria are systematically discussed in this paper.
