摘要
分析国内外现有碾压混凝土重力坝的渗控结构型式及运行效果并进行了综合评判。用渗流有限元法对不同渗控结构渗流场进行了分析比较，指出在碾压混凝土坝渗流控制中，防止渗漏仅仅是一个方面，更重要的是降低坝体的渗透压力。提出应将面板堆石坝的设计思想引入碾压混凝土坝的设计中。
On the basis of systematical analysis of the behavior of existing structures for seepage control,several cases of seepage control are studied,and the results are interpreted in detail.It is indicated that the key point in seepage control design for high RCCD is to reduce the seepage pressure acting on the bedding joint of RCC,and the concept of controlling the seepage flow in the zone of the watertight face and drainage systems of dams is presented.
