摘　　要：针对碾压混凝土坝的渗流特性及其渗控设计的复杂性,在多年理论研究工作的基础上对国内外多座已建大坝工程所用的防渗结构型式和运行情况进行介绍,并对不同典型防渗结构型式的主要优缺点作了分析,推荐了既有较好防渗功能又能充分发挥碾压混凝土施工优点的优选防渗结构型式.In consideration of the seepage properties of rollercompacted concrete dams (RCCDs) and the complicacy of seepagecontrol design, an introduction is given to the practice in seepage prevention structures and their performances in projects of some existing dams at home and abroad. The main advantages and disadvantages of some typical seepage prevention structures are analyzed through comparison. Finally, an optimum seepage prevention structure for RCCDs is recommended, which can bring the main advantages of rollercompacted concrete construction into full play.
