摘　　要：洪家渡水电站面板堆石坝处于高山峡谷岩溶地区,坝高179 5m,河床宽高比2 38。在坝基开挖设计中,通过认真研究趾板区的地形地质条件,将趾板上部高边坡、趾板基础及趾板下游的堆石体边坡开挖统筹考虑,一次开挖完成。在坝基处理中,根据开挖揭露的多种不良地表形态和地质缺陷,制定了相应措施,满足了工程要求。这些设计方法和处理措施将为岩溶峡谷地区修建面板堆石坝积累有益的经验。The face rockfill dam of Hongjiadu Hydropower Station with a height of 1795 m and ratio of width to height 238 located at karst area where are high mountains and gorges.When dam foundation excavation was designed, conscientiously researching topographic and geological conditions, the designer selected the design that high side above plinth, plinth foundation and the side of rockfill body at downstream of plinth would be excavated at same time. When dam foundation was treated the designers adopted relevant measures to meet the requirements of engineering according to many unfavorable topographic and geological conditions discovered in excavation.The design method and treatment measures have accumulated helpful experience for constructing face rockfill dam in karst gorge areas.
