2、太子河干流修建观音阁水库。观音阁水电站工程设计的内容包括径流调节和水能计算、水轮发电机组的选择、洪水调节、坝体设计、水电站厂区厂房布置、安装间楼板结构计算。通过计算可得观音阁水库的兴利库容为，正常蓄水位为；选择的水轮机的型号为HL240-LJ-180，发电机型号为SF8-12/312；设计洪水位为，校核洪水位为；坝体由挡水坝段、溢流坝段和电站坝段组成，溢流坝段坝体采用挑流消能型式；水电站厂房采用坝后式厂房形式，电站厂区主要包括主厂房、副厂房、尾水渠、主变压器、高压开关站和对外交通线等；安装间采用梁格式结构布置，并为转子检修设置了

3、水平圆弧梁，梁下有八个支柱。关键词：径流调节；水轮发电机组；洪水调节；厂房布置；楼板配筋-I-观音阁水电站工程设计说明书TheEngineeringDesignofGuanyingeHydropowerStationAbstractTaiziRiverisabigbranchofLiaoheRiver,itliesintheeastsideofthedownstream.Themulti-annualmeanamountofrunoffofTaiziRiverbasinisabout4.6billionm³,whichisthe
