I第1页贵州樱子水电站设计（大坝、厂房部分）之三(正常蓄水位：1382.249m)摘要贵州樱子河电站水库无防洪、航运、灌溉等任务，电站建成后的主要任务是发电，水库的正常蓄水位及设计洪水位1388.40m，校核洪水位1390.164m，死水位1385.00m，水库的兴利库容为95万m3，水库的死库容为679万m3总库容为813万m3；电站的多年平均发电量为6470万kW·h，装机容量为1.6万kW，保证出力为1496kW，设计水头是39.8m，设计援用流量为46.0m3/s，大坝和水电站的工程大小均属于小(1)型，且工程级别为Ⅳ级。该电站的主要建筑物有：冲沙底孔、主副厂房，升压站，大坝、引水建筑物。大坝是一变圆心变外半径的双曲拱坝，坝体的最上面高度为69.347m，坝体的最下面厚度为11.600m，坝顶宽5.000m。为防止坝基渗漏，在坝基靠近上游侧进行帷幕灌浆，并且为了减少坝基的扬压力，灌浆帷幕的后面是排水孔。樱子水电站为径流式电站，用混凝土双曲拱坝住当水位形成发电水头，应用左岸隧洞引水发电，厂房和开关站均为地上式。本次毕业设计为贵州樱子河水电站的初步设计，设计内容主要有：引水建筑物布置、水电站厂房设计、工程总枢纽布置、大坝布置及应力和稳定计算、冲沙底孔布置。关键词：双曲拱坝，引水建筑物，取水口，冲沙底孔，厂房。II第2页AbstractGuizhouyingziRiverhydropowerstationreservoirfloodcontrol,shipping,irrigationandothertasks,powerstationafterthecompletionofthemaintaskispower,thereservoirnormalwaterlevelandthedesignfloodlevel1389.00mandcheckfloodlevel1389.64mwaterlevel1385.00mdie,deadstoragereservoirs679millionm3,Hennessycapacity95millionm3,withatotalcapacityof813millionm3;plantannualaveragegeneratingcapacityfor64.7millionkW/h,installedcapacityis1.6millionKW,ensuresthattheoutput1496kW,designheadis39.8m,designreferenceflow46.0m3/s,reservoirandpowerstationengineeringscalearesmall(1)type,andtheengineeringleveltothefourthgrade.Themainbuildingofthepowerstationare:dam,diversionstructures,sandbottom,mainandauxiliarypowerplant,boosterstation.Thedamisadoublecurvaturearchdamvariablecentresoutsideradius,themaximumdamheightof69.347m,bottomthickness11.600m,thewidthof5.000m.Topreventdamfoundationleakage,thecurtaingroutingiscarriedoutnearthedamfoundation,andtheupliftpressureofdamfoundationisreduced,andthedrainageholeisarrangedaftergroutingcurtain..YingzihydropowerstationonRegulatingRunoffofhydropowerstation,theconcretehyperbolicarchdamtointerceptwatergenerationhead,theleftbankdiversiontunnel,workshopandswitchstationareontheground.ThegraduationdesignforthepreliminarydesignofGuizhouyingziRiverhydropowerstation,designcontentmainlyincludes:damlayoutandforceandstabilitycalculation,redsandbottomholelayout,diversiontunnellayout,hydropowerstationplantdesign,engineering,generallayoutoftheproject..III第1页Keywords:hyperbolicarchdam,diversionstructures,sandbottom,plant1第1页目录2第2页摘要................................................................IABSTRACT...........................................................II第一章综合说明.....................................................31.1概述...........................................................31.1.1工程概况..................................................31.1.2设计要求....................................................41.2工程特性表.....................................................41.2.1水库特性表.................................................41.2.2樱子河径流年内分配表.......................................41.2.2樱子河电站设计洪水成果表.................................41.2.4施工设计洪水成果表..........................................5第二章设计...
