钟吕水利枢纽堆石坝设计说明书

水利水电工程专业毕业设计-1-摘要本次设计主要是为了开发利用B江流域的水利资源，建设一个以发电为主，同时兼顾灌溉、供水、防洪及养殖等综合利用效益的跨流域开发的水利水电枢纽工程。在毕业设计指导书和老师的指导下，进行了水利枢纽的设计，枢纽的概况如下：B江水利枢纽为复合土工膜防渗堆石坝最大坝高54.7m，装机6400kW，电站设计水头174米，保证出力1461kW，装有两台3200kW机组，正常蓄水位276.3m，主坝长214.5米左右，上游边坡1：1.5，下游边坡250m高程以下1：1.55，250m高程以上1：1.52。本次设计主要内容为：经洪水调节确定坝顶高程和泄洪道高程；坝型的比选，确定为复合土工膜防渗堆石坝；第一主要建筑物的设计，进行了坝轴线定线，坝坡稳定分析，副坝设计，趾板设计，工程量计算等工作；施工组织设计，其中有导流隧洞布置，施工总进度计算等工作；泄水建筑物的设计。重点对本次设计专题—投标报价书进行了计算及编写。复合土工膜防渗堆石坝是一种新的坝型，其防渗材料---复合土工膜的设计、施工、质量控制是该类坝型的技术关键，在本设计说明书第六章第三节有详细说明。本次设计以一般混凝土面板堆石坝和一些已建复合土工膜堆石坝为参考，在注重各细部独立分项设计的同时，综合考虑了整体工程的统一性。在专题的编写中参考其他工程的的投标文件，按照规范对投标报价书进行了完整有序的编写。在设计过程中既充分运用了所学知识，如水力学、静力学、水工钢结构、工程施工等，又运用了许多研究方法，如高切林法、试算法等。广泛参考了堆石坝设计、施工等相关书籍，并在规范规定内设计，体现了本设计的科学性、规范性、严谨性。关键词：复合土工膜；堆石坝；调洪演算；边坡稳定；导流；施工组织设计；投标报价钟吕水利枢纽堆石坝设计-2-AbstractThepurposeofthisdesignistodevelopthewaterresourcesofBJiangBasin，constructingapower-based，takingintoaccountirrigation，watersupply，floodprotectionandaquacultureEtc.ofcomprehensiveutilizationefficiency，suchasthedevelopmentofinter-basinwaterconservancyandhydropowerproject.Withtheguidebookofgraduationproject，thewatercontrolprojecthasbeendesigned，summarizedasfollows:BJiangProjectisacompositegeomembraneimpermeablerock-filldamheightof53.0m，installed6400kW，thedesignheadofpowerstationis174m，thefirmcapacityis1461kW，withtwoengineunitof3200Kw，thenormalwaterlevelis276.5m，thelengthofthemaindanisabout227m，theupstreamslopeanddownstreamslopebothare1:1.52.Theprimarycoverageofthedesignis:ascertainthecrestelevation;Pa-selection，Impermeablecompositegeomembranerockfilldamhasbeenindentified;thefirstmajorbuildingdesign，thedamaxishasbeenalignmented，Auxiliarydesign，PlinthdesignandEngineeringCalculationhasbeenfinished;constructionorganizationdesign;Dischargestructuredesign.CalculationandpreparationofthebookfortenderofferwhichisThefocusofthisdesignhasbeenprepared.Impermeablecompositegeomembranerockfilldamisanewtypeofdam，theimpermeablematerial—compositegeomembranethedesign，construction，qualitycontrolisthedamofsuchkeytechnologyinthedesignofChapterVIofthethirdstatementFestivalareexplainedinmoredetail.ThedesignisrefertothegeneralCFRDandsomeofgeomembranerockfilldamwhichhasbeenbuild.Payattentiontothedetaildesignoftheindependentsub-item，atthesametime，consideringtheunityoftheoverallproject.Inthedesignofthetopic，referencingthetenderdocumentsthathadbuild，thebookfortenderofferhasbeenpreparedunderstandards.Inthedesignprocesswhichisfulluseoftheknowledge，forexampleHydraulics，Statics，EngineeringConstructionandsoonandthemethodswhichhasbeenused，forexampleTestAlgorithmandsono.Extensivereferencetothedamdesign，constructionandotherrelatedbooks，anddesignwithintheprovisionsregulating，thedesignreflectsthescientific，standardizedandtneRigor.Keywords:compositegeomembrane;rockfilldam;floodrouting;slopestability;tenderdocuments;thediversion;tenderoffer水利水电工程专业毕业设计-3-目录第一章综合说明-1-1.1工程特性表..........................................................................................................-1-1.2建设目的和依据................................................................................................-3-1.3建设的条件..........................................................................................................-3-1.4建设的规模及综合利用效益..............................................................................-4-第二章自然地理条件-5-2.1地形条件..............................................................................................................-5-2.2水文特性..............................................................................................................-5-2.3工程地质条件......................................................................................................-6-2.4气象、地震及其他............................................................................................-10-第三章设计条件和设计依据-11-3.1设计任务............................................................................................................-11-3.2设计依据............................................................................................................-11-第四章洪水调节计算-12-4.1洪水调洪演算..................................................................................................-12-4.2洪水标准分析....................................................................................................-14-4.3洪水建筑物的型式选择....................................................................................-14-4.4调洪演算及泄水建筑物尺寸（孔口尺寸/堰顶高程）的确定.......................-15-第五章主要建筑物型式选择及枢纽布置-20-5.1枢纽等别及组成建筑物级别............................................................................-20-5.2坝型选择............................................................................................................-20-5.3泄水建筑物型式选择........................................................................................-26-钟吕水利枢纽堆石坝设计-4-5.4水电站建筑物....................................................................................................-27-5.5枢纽方案的综合比较........................................................................................-27-第六章第一主要建筑物设计-28-6.1大坝轮廓尺寸及防浪墙设计......................
