摘要
2008年完工的水布垭混凝土面板堆石坝是当前世界上最高的面板堆石坝。本文通过大坝面板、趾板及其止水结构设计,坝体断面分区及其水力过渡设计,坝基渗流控制设计的介绍,详细地阐述了水布垭面板堆石坝的渗流控制体系。自水库蓄水以来,大坝已经经历了较长时间的高水位运行,渗漏量一直很小,没有产生渗流异常现象,说明渗流控制体系已经成功地形成并且运行正常。
Shuibuya concrete faced rock-fill dam completed in 2008 is the highest CFRD in the world at present.This paper demonstrates the seepage control system of this dam： design of the face /toe slabs and the joint sealing structures,monolith design,hydraulic transient scheme,and the principle and measures of dam foundation seepage control.Since the reservoir impounding,the dam has been experienced several months of high storage level.Dam leakage is rather low and no abnormal seepage has been ever observed,which shows a success of the seepage control system.
