摘　　要：大花水水电站所处地区地形不对称,地质条件复杂,下泄流量大,为此,采用了河床拱坝+重力坝的组合坝型,泄洪建筑物布置于拱坝坝身,采用3表孔+2中孔交错的布置形式,回避了地质缺陷带来的问题,解决了狭窄河谷大泄量泄洪建筑物的布置难题。Due to the unsymmetrical topography of the area where the Dahuashui Hydroelectric project is located and complex geological conditions and great discharge flow, a combination of river bed arch dam and gravity dam was adopted for the project with discharging structures including 3 surface outlets and 2 middle outlets staggered on the proper of the arch dam so as to avoid the geological problems and difficulties in arrangement of high discharging structures in steep and narrow valleys.
