楚林楚河水利枢纽设计说明书

摘要林江是我国大河流之一，其干流全长700公里，流域面积17400平方公里；楚河是林江的重要支流，流经林江的上下游地带，全长250公里，流域的面积为7200平方公里。楚河开发计划是配合林江而制定的。楚河楚林水利枢纽就建立在楚河和林江汇流处的楚林。枢纽属一等工程，以防洪和发电为主，兼有航运等综合效益。其主要建筑物有：混凝土实心重力坝、引水建筑物、泄洪建筑物、放空建筑物、过坝建筑物和电站厂房等枢纽按千年一遇洪水设计，五千年一遇洪水校核。水库正常蓄水位178.0米，设计洪水位179.3米，校核洪水位180.13米。电站装机3台2.4万千瓦，总装机72000千瓦。船闸可以保证80吨级驳船通航。主体建筑物实体重力坝坝顶高程182.04米，最大坝高46.04米；泄洪采用表孔，共三孔，每孔宽12米，堰顶高程170.92米；放空采用深孔，设一孔，宽3.5米，高4米，底板高程151米；电站引水采用坝内压力钢管，钢管直径4.5米；电站厂房为坝后式。本设计对枢纽的主体建筑物进行了认真的方案比选和详细的尺寸设计，并对所设计的建筑物进行了安全校核，保证建筑物的安全运行。同时对水电站和施工导流进行了简要的设计。[关键词]林江楚河楚林水利枢纽大坝AbstractLinjiangRiverisoneofthelargestreamflowinourcountry,whichhas700kilometerslong,anddrainageareacoversabout174000km2.ChuheRiver,whichisontheupstreamoftheLinjiangRiver,isthemostimportantanabranchontheLinjiangRiver,ithas500kilometerslongandit’sdrainageareacovers7200km2.ThedevelopmentplanofChuheRiverisdeterminedontheLinjiangRiver.TheChuheChulinwaterprojectplanisbuiltattheChulin,ofwhichtheaccordantjunctionofChuheRiverandLinjiangRiver.TheChuheChulinwaterprojectplanisthefirstclassproject,it’smainfunctionsarefloodcontrolandpowergeneration.Themainbuildingincludes:theconcretegravitydam,thediversionheadbuilding,theemptyingoutletbuildingandwaterpowerplantetc.Waterprojectplanisdesignedaccordingtomeetingflooddesignonceinmillennium,andmeetfloodcheckonceinfivethousandyears.Thenormalwaterleveloftheprojectis178.0m,thedesignfloodlevelis179.3m,andthecheckfloodlevelis180.13m.Thetotalvolumeofthepowergenerationunitsis72000KW.Theshipboxcanguaranteethat80tonsofbargesgetthrough.Thisdesignhascomparedseveralavailableprojectsearnestlyanddesigndetailedsize.Atthesametimeitchecksthesafety,andensurethesafeoperationofthebuilding.Simultaneously,thepaperdesignthewaterpowerstationanddiversionworkbriefly.[Keywords]LinjiangRiverChuheRiverWaterprojectplanDam目录第一章总述············································································································································································································································································································································································································································································································································································································································1111第二章基本资料············································································································································································································································································································································································································································································································································································································22222.1坝址地形······················································································································································22.2坝址地质······················································································································································22.3水文气象······················································································································································22.4当地材料分布情况······································································································································42.5交通运输情况及施工条件··························································································································42.6水利水能计算资料······································································································································42.7船闸设计资料··············································································································································5第三章坝型选择与主要建筑物的选择························································································································································································································································································································································································································································66663.1确定枢纽等别和建筑物的级别··················································································································63.2坝型的选择··················································································································································63.3枢纽主要建筑物的选择······························································································································8第四章调洪演算·······························································
