| 摘 要： | 解决渗流问题是碾压混凝土坝技术发展的关键。文章利用节点虚流量法和改进的排水孔模拟技术，对碾压混凝土坝体渗流场进行了精细的有限元分析。分析表明，采用变态混凝土与二级配碾压混凝土组合防渗结构防渗能满足设计要求，该防渗形式结合其后排水孔幕，为大坝的渗控安全提供了有力的保证。

| Abstract: | it is key of development high RCC dam to find the seepage control measure to solve seepage, the effectiveness of the seepage control schemes of the combination of distorted concrete face slab on dam up stream side with two graded aggregate RCC was analyzed by using procedure of nodal virtual flux of global iteration and improved method of drainage hole in detail; Mean while, the seepage control effect of drainage curtain in the dam body was also studied, The more reasonable seepage prevention scheme is recommended, |
