水布垭水利枢纽工程总体布置方案研究

系统地介绍了水布垭水利枢纽的布置方案研究过程与最终的枢纽布置方案.根据水布垭工程的地形地质条件,在枢纽布置总格局研究的基础上,确定了左岸布置溢洪道和导流隧洞,右岸布置地下电站厂房与放空洞的枢纽布置格局;通过坝轴线的比较,大坝布置在水布垭峡谷河段偏上游位置更有利于其它主要建筑物的布置与调整;通过大量的方案比较论证,水布垭枢纽布置为:大坝采用混凝土面板堆石坝、左岸布置台阶式窄缝挑流消能溢洪道、右岸布置引水地下电站与放空洞.

Research for general arrangement of Shuibuya hydroproject

Systematically introduced the research process of the layout scheme of Shuibuya hydroproject and the last project layout scheme.According to the geographical and geological condition of Shuibuya hydroproject,on the base of research for general layout,it is determined that arranging spillway and water diversion tunnel on the left bank,the emptying tunnel for underground power house on the right;through the dam axis comparison,it is concluded that arranging the dam a little more upstream in Shuibuya river reach in the canyon is more favorable to arranging and adjusting of other main structures;through a great deal of comparison and demonstration,the arrangement of Shuibuya hydroproject is determined as: concrete faced rockfill dam,step-type narrow ski-jump spillway on left bank,an water diversion underground power station and empty tunnel on right bank.
