摘　　要：针对猴子岩面板堆石坝的坝体、坝基以及防渗帷幕等结构进行了三维建模。采用饱和稳定渗流有限元法、渗流量插值网格法对猴子岩面板堆石坝进行了三维渗流计算分析。重点研究了面板和防渗帷幕联合作用下渗流场分布特征和防渗效果,探讨了面板出现裂缝、垫层渗透性等对坝区渗流场的影响。A 3D numerical model is built for the concrete face rockfill dam of Houziyan Hydropower Station considering the structures of dam body, dam foundation and impervious curtain, and the saturated stable seepage finite element method and leakage interpolation mesh method are adopted to simulate the three dimensional seepage field of Houziyan CFRD based on the model. The seepage field distribution and seepage control effect of impermeable system of dam are emphatically studied, and the effects of hypothetical cracks in concrete slab and cushion material＇s permeation characteristics on seepage field in dam area are also discussed.
