摘　　要：猴子岩水电站混凝土面板堆石坝地处狭窄河谷,两岸地形不对称,河谷宽高比约1. 25,最大坝高223. 5 m,为目前世界第二高混凝土面板堆石坝,趾板结构布置和结构设计存在一定难度。为此,结合猴子岩水电站坝址区地质地形条件及工程特点,概括和阐述了猴子岩混凝土面板堆石坝趾板的布置、定线、宽度、厚度、趾板混凝土、分缝、配筋、河床趾板回填基础(趾墙)、趾板基础处理等设计成果,为类似工程提供参考。The dam of Houziyan Hydropower Station is the second highest concrete face rockfill dam in the world with a height of 223. 5 m. The dam is located in the narrow valley, where the terrain on both sides is asymmetric and the ratio of width and height of valley is about 1. 25. There are some difficulties in layout and structure design of toe slab. Based on the geological and topographic conditions of dam site and project characteristic, the design of dam toe slab is introduced from the aspects of layout, base line selection, width, thickness, concrete, joints, reinforcement, backfill foundation （toe wall） at riverbed, and foundation treatment for providing reference to similar engineering.
