摘　　要：藤子沟水电站大坝为混凝土双曲拱坝,最大坝高124.0 m,拱坝厚高比为0.171,目前为中国同等规模中最小。文章结合藤子沟工程的地质特征,介绍了拱坝总体布置、坝体应力及变位分析、坝肩抗滑稳定分析及坝基地质缺陷处理等。As the water retaining structure of Tengzigao hydropower project,the conventional concrete double-curve arch dam is 124.0 m high at maximum,with a high-thick ratio of 0.171,the smallest in same scale projects in China.Based on the geological features of the project,this paper presents the general layout of the arch dam,dam body stress and displacement analysis,abutment stability against sliding analysis,and treatment of dam foundation geological defects.
