1、摘 要乌溪江水电站座落于浙江省乌溪江湖南镇,属于梯级开发电站,根据地形要求,其开发方式为有压引水式。坝区地质条件较好,主要建筑物(砼非溢流坝),泄水建筑物(砼溢流坝),引水建筑物(有压引水遂洞,调压室),地面厂房。水库设计洪水位238m(千年一遇),相应的下泄流量4800m3/s;校核洪水位240m(万年一遇),相应的下泄流量8500m3/s;正常挡水位232m.本设计确定坝址位于山前峦附近,非溢流坝坝顶高程242m。坝底高程112m。最大坝高130m。上游坝坡坡度1:0.1,下游坝坡坡度1:0.80,溢流坝堰顶高程224.54m。引水遂洞进口位于坝址上游凹口处,遂洞全长1290m。洞径8.6
2、m,调压室位于厂房上游260m左右处,高程255m的山峦上,型式为差动式(大、小井分离式)。厂房位于下游荻青位置。设计水头96m,装机容量45.6=22.4万Kw,主厂房净宽18m,总长77.5m。水轮机安装高程115.78m,发电机层高程125.5m,安装场层高程129m(比下游校核洪水位128 m略高)。厂房附近布置开关站,主变等。受地形限制,为了减少开挖量,尾水平台兼作公路用,坝址与厂区通过盘山公路连接,形成枢纽体系。由此可见,本设计是合理可行的。关键词:水利枢纽;挡水建筑物;泄水建筑物;稳定;应力;水轮机;选型;引水隧洞;调压室;厂房;发电引水隧洞。Abstract The Wuxij
