摘　　要：大岗山水电站坝址区地形地质条件复杂,地震烈度高,枢纽布置难度大。根据坝址区水文地质条件,枢纽布置采取混凝土双曲拱坝挡水,坝身深孔、右岸泄洪洞泄洪及水垫塘、二道坝消能防冲,以及左岸引水发电系统,很好地利用了上、下游两个河湾地形,使左岸引水发电系统和右岸泄洪建筑物都能裁弯取直布置,在保证水流顺畅的同时,节约了工程投资。The design of hydraulic structure layout of Dadangshan Hydropower Station is difficult because of complex topographical and geological conditions and high earthquake intensity of dam area. The project layout is consisted of double curvature arch dam, dam flood discharging outlets, right-bank flood discharging tunnel, plunge pool and subsidiary dam for energy dissipation and left-bank water diversion-generating system. This layout program can fully utilize the terrain of upstream and downstream river bends to straighten the arrangement of left-bank water diversion-generating system and right-bank flood discharging tunnel, and save project investment.
