摘　　要：沥青混凝土面板防渗断面形式一般有简式和复式之分。考虑基础岩层中普遍分布有软弱夹层,张河湾抽水蓄能电站上水库采用沥青混凝土面板全库盆防渗,并对防渗面板断面形式进行了创新性的优化设计,成功实现以(防渗)整平胶结层替代下防渗层和原整平胶结层,减少了一层,取得了良好的防渗效果和经济效益,同时,对工程安全运行具有重要意义。There are two structures of simple and composite type for bituminous concrete impervious facing in practice. After considering the weak intercalations in strata, the upper reservoir of Zhanghewan Pumped-storage Power Station adopts full basin anti-seepage with bituminous concrete facing, and the design of facing structure is innovatively optimized, in which, the second impervious layer and leveling and binder layer in traditional structure is substituted by new leveling and binder layer with certain impervious capacity. The practical operation of the reservoir shows that the new design has a good impervious effect and economic benefit, and at the same time, it also guarantees the safe operation of project.
