摘　　要：针对碾压混凝土及碾压混凝土坝的渗流特性 ,结合碾压混凝土坝防渗设计的主要原则 ,评述了国内外碾压混凝土筑坝过程中所采用的主要防渗结构型式 ,并总结出能满足渗控要求 。Taking into account of the seepage properties of roller compacted concrete and the design criteria for seepage prevention and control of roller compacted concrete dams, in this present paper the authors mainly focus on the study on types of seepage prevention structures of roller compacted concrete dams.At first,the main typical seepage prevention structures practically adopted are introduced and interpreted,then by comparison of analyses and the authors' knowledge gotten from their own research work for many years in this area,the authors recommend optimum types of the seepage prevention structures for high roller compacted concrete gravity dams.They could essentially meet the demands of seepage control and make rapid construction of roller compacted concrete dams be brought to full play.Finally,two different structural design schemes for the seepage control are recommended.
