水利水电专业毕业设计前言

[水利专业毕业留言]晴朗的夏夜，不妨仰望星空，使你的心灵得到净化。像少年时一样，常常撒腿在亮晶晶的雨珠中奔跑吧。你会感到你的心是永远年轻的。不要奢望有许多人喜欢你--其实只要有一些人喜欢...+阅读

呵呵我毕业设计的时候没写前言就有个摘要关键词：水利枢纽；水能设计；多年调节；水库调度；挡水建筑物；泄水建筑物；稳定；应力；水轮机；选型；引水隧洞；厂房；尾水管。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234.55m千年一遇），相应的下泄流量5480m3/s；校核洪水位238.16m（万年一遇），相应的下泄流量8435m3/s；正常蓄水位230m. 本设计确定坝址位于山前峦附近，非溢流坝坝顶高程238.35m，防浪墙顶高程239.35m，坝底高程111m，最大坝高127.35m。上游坝坡为折坡，折坡度1:0.2，下游坝坡坡度1:0.8，溢流坝堰顶高程224m。引水遂洞进口位于坝址上游凹口处，遂洞全长1150m。

洞径10.6m. 厂房位于下游荻青位置。设计水头95.15 m，装机容量4*7.5=30万kw，主厂房净宽22.00m。水轮机安装高程115.36m，发电机层高程127.1m，安装场层高程127.1m（高于下游千年一遇设计洪水位）。厂房附近布置开关站，主变等。由此可见，本设计是合理可行的 Abstract The Wuxijiang hydropower station is located in HuNan Town in ZheJiang province ,which belongs to a chain of exploitation . According to the demand of topographic form ,I choose diversion hydropower station . The geology condition is good .The main construction conclude the water retaining structure (the concrete non –over-fall dam) ,the release works (the concrete over –fall dam) ,the diversion structure (pressure seepage tunnel ,the surge-chamber ) ,and the surface power station . The design water level is 234.55 m ,its corresponding flow amount is 5480m3/s .The check level is 238.16 m ,its corresponding flow is 8435m3/s .The regular water retaining level is 230 m . The dam site is near the former saddle .The crest elevation of the non-over-fall dam is 238.35.0 m ,and the base elevation is 111m ,The max height of the dam is 127.35 m ,The upstream dam slope is 1:0.1 ,the downstream dam slop is 1:0.8 ,the spillway crest elevation is 224.0 m .The inducer of the seepage tunnel is located at the recess place ,The length of tunnel is 1150 m ,the diametric of which is 10.6 m . The workshop building is located at downstream ,the design level of the turbine is 95.15 m , the equipped capacitor is 30*104kw ,the clean width is 22 m , its whole length is 73.7m . The fix level of the turbine is 127.1 m , and the height lf dynamo is 127.1 m . Near the workshop building , there are switch station and the main transformer and so on .
