摘　　要：通过对新疆ARTS水利枢纽工程的超高面板堆石坝建立坝体、防渗系统模型进行渗流分析,结果表明:各个工况下混凝土防渗体、坝体、砂砾石覆盖层的孔压等值线图、等势线图、流速矢量线分布规律合理,下游坝脚出逸点的最大水力梯度imax均小于允许比降,河床段防渗系统折减了97%的水头,认为防渗系统起到了很好的防渗效果,坝料分区、坝基处理较为合理,渗控设计符合规范要求。In this paper,seepage analysis is carried out for the model of dam body and seepage-proof system of super-high face rockfill dam of ARTS hydraulic complex project in Xinjiang.The results show that the pore pressure isoline,potential isoline and velocity vector line of concrete impervious body,dam body and gravel cover are reasonable under various conditions.The maximum hydraulic gradient at the escape point of the downstream dam foot is less than the allowable gradient,and the seepage-proof system in the riverbed section reduces the head by 97%.Therefore,it can be considered that the seepage-proof system has played a very good seepage-proof effect,the partition of dam materials and the treatment of dam foundation are reasonable,and the seepage control design meets the requirements of specifications.
