| 摘 要： | 以羊曲水电站为依托，通过建立水电站面板堆石坝的三维渗流有限元模型，计算分析了坝体及
其坝基的三维稳定渗流场特性，得到了坝体和坝基的位势分布、坝体各料区的渗透坡降及渗透流量等。
分析了防渗帷幕和坝基岩体渗透参数对渗流场的影响。结果表明，坝体、坝基及左右岸坝肩的防渗措施
均满足要求。

| Abstract: | Through the development of a 3-D seepage finite element model of a concrete faced rockfill dam ,this paper calculated and analyzed the characteristics of the stable seepage field of the dam body and its foundation .The equipotent distribution of the seepage field ,seepage gradient of dam body and seepage discharge were also obtained .The effects of the seepage parameter to impervious curtain and rock mass of dam foundation were then analyzed .The result shows that the seepage proofing efficiency of the dam can meet the requirements . |
