摘　　要：　榆树沟水库工程是我国建成并过流的第一座溢流混凝土面板堆石坝。其设计特点是:根据坝址实际地形、地质条件,将溢洪道直接布置在堆石坝体上,同时,充分利用开挖弃料,简化了枢纽布置、加快了施工进度、降低了工程造价;在坝体溢洪道结构设计上,采用了曲线型实用堰、叠瓦式构造连接的掺气槽、阻滑板和预埋锚固拉筋、高性能混凝土等措施,从而提高了溢流堰泄流能力、抗蚀减振能力和泄槽适应变形的能力,增加了坝体溢洪道的安全稳定性。Yushugou reservoir project is built in our country,it is the first overfall Concrete Face Rockfill Dam(CFRD) which has been carried out flood discharge.Design characters of the project are that according to dam site terrain and geologic condition, the spillway is disposed on the dam directly. At the same time ,using local discardable material adequately,predigesting pivot disposition,construction process was accelerated,the project investment was cut down;In structure designs of the spillway on the dam, curve utility weir, chute of imbricate structure,anti-slide slab and embedded reinforcing bar,and concrete with better quality were adapted. Thereby improving overfall weir flood discharge ability,anti-cavitation and anti-quiver ability,and a ability to adapt the dam deformation were improved. The safety stability on the spillway was built up.
