摘　　要：以察汗乌苏水电站为例,针对覆盖层上混凝土面板堆石坝坝体和坝基防渗系统的布置关系到防渗效果问题,基于三维有限元法建立了相应的模型,模拟分析了防渗墙、帷幕、排水系统在不同布置方案下的渗流场,论证了防渗系统的有效性,经比较分析得出最优的布置方案。Taking the Chahewusu hydropower station for an example, the effect of seepage prevention is analyzed by considering the different seepage control system layout schemes of the dam foundation and the CFRD built on deep overburden layer. Based on the 3D finite element method, the corresponding simulation models are established to analyze the dam seepage field under the different layout schemes of the concrete cut off wall, curtain and the drainage system. Then it demonstrates the effectiveness of the seepage prevention system. Finally, the optimal arrangement plan of concrete cut off wall, curtain and drainage is determined.
