摘　　要：鉴于反滤层是防止土石坝渗透破坏的有效措施 ,设置反滤层的依据是被保护料的性质和滤层准则。本文着重叙述了滤层准则研究、应用 4个发展阶段的特点和一些代表性滤层准则以及鉴别是否是宽级配、自滤、内部稳定料和土料调整方法。In view of that filter is an effective measure to protect earth rockfill dams from seepage failure,the filter is provided on the basis of the property of protected material and the filter criteria.The paper describes the research of filter criteria, the features of 4 development stages and some typical filter criteria as well as identification of wide gradation,self-filtration internal stabilized material and adjustment of earth material.
