摘要
阿尔塔什水利枢纽泄水建筑物水头高、流速大、出口覆盖层深度大,泄水建筑物布置需兼顾泄洪、排沙、水库放空、生态基流泄放等多种任务。根据地形、地质及水文条件进行泄洪系统布置方式的论述,经多方案比选确定泄水建筑物的最终布置格局:左岸山体由岸边到岸里分别为2~#深孔(导流洞改建)、中孔、1~#表孔、2~#表孔。研究成果对阿尔塔什水利枢纽工程泄洪系统的合理布置具有重要意义。
The discharge structure of Altash Water Control Project possesses the characters of high head,high velocity,andthick overburden. The layout of discharge structure need to consider a variety of factors such as flood discharge,sediment ejec-tion,reservoir emptying and ecology base flow discharge. Discussed the layout of flood discharge system according to topogra-phy,geology and hydrology,and determined the layout method by scheme comparison finally,which is 2~#bottom outlet(recon-struction of diversion tunnel),medium outlet,1~#surface outlet,2~#surface outlet. The study result has a reference value for thelayout of flood-discharge system of Altash Water Control Project.
