土石坝毕业设计

摘要土石坝泛指由当地土料、石料或混合料，经过抛填、辗压等方法堆筑成的挡水坝。当坝体材料以土和砂砾为主时，称土坝、以石渣、卵石、爆破石料为主时，称堆石坝；当两类当地材料均占相当比例时，称土石混合坝。土石坝是历史最为悠久的一种坝型。近代的土石坝筑坝技术自２０世纪５０年以后得到发展，并促成了一批高坝的建设。目前，土石坝是世界坝工建设中应用最为广泛和发展最快的一种坝型。因农业生产的需要，云南大姚县拟在县城东北7km的金碧镇施永屯办事处龙林村兴建一个土石坝型灌溉水库。在对本处的自然地理与水文特征、工程地质情况及周围的建筑材料了解之后。经过详细的分析之后，选取了坝轴线并进行了枢纽布置。依据毕业设计要求利用内插法进行了调洪演算，得到了设计洪水位与校核洪水位。进行了枢纽布置，划分了工程等级与主要建筑物等级。深入的进行了坝体剖面设计，计算出了坝顶高程。然后又进行了渗流计算、稳定计算、细部结构设计、坝身构造设计、输水建筑物设计以及溢洪道布置等十章内容。具体见设计书。关键词：土石坝；调洪演算；输水建筑物。AbstractEarthdamreferstolocalsoilmaterial,stoneormixture,afterthrowingfilling,rollingandothermethodspiledintodams.Whenthedammaterialtothesoilandgravel-based,saidthedam,whengravel,pebbles,stoneblastingmainlyknownrockfilldam;Whentwocategoriesaccountforaconsiderableproportionoflocalmaterials,theknowndebrismixeddam.Earthdamisoneoftheoldesttypeofdam.Moderntechnologyhasbeendevelopeddamembankmentdamsincethe20thcentury,50yearslater,andcontributedtoanumberofdambuilding.Currently,theconstructionofearthdamdamistheworld'smostwidelyusedandoneofthefastestgrowingtypeofdam.Becauseoftheneedforagriculturalproduction,YunnanDayaoCountyproposestoconstructanearthdamirrigationreservoirinthenortheastofthecountytownSplendorLongLam,Tuen7kmofoffice.Afterthenaturalgeographicalandhydrologicalcharacteristicsofthedepartment,engineeringgeologyandunderstandingofthesurroundingbuildingmaterials.Afteradetailedanalysisofthedamaxisandselecttheprojectlayout.Graduationrequirementsbasedontheuseofinterpolationmethodoffloodrouting,gotthedesignfloodlevelandcheckfloodlevel.Conductedaprojectlayout,dividingtheprojectlevelandthelevelofthemainbuilding.Conductedathoroughcross-sectionofdamdesign,calculatethecrestelevation.Andthenconductedaseepagecalculation,stabilitycalculation,detaildesign,structuraldesignofthedambody,waterspillwaybuildingdesignandlayout,morethan10chapters.Seedetaileddesigndocument.Keywords:earthdam;floodrouting;conveyancebuildings.1目录前言摘要1.基本资料.....................................................................................................................................11.1自然地理与水文气候特性................................................................................................11.1.1流域概况......................................................................................................................11.1.2水文特征......................................................................................................................11.1.3其他相关的水文成果..................................................................................................21.2工程地质情况.....................................................................................................................21.2.1区域地质情况..............................................................................................................21.2.2水库工程地质..............................................................................................................31.2.3坝址地质条件..............................................................................................................31.2.4地震情况......................................................................................................................41.3建筑材料.............................................................................................................................41.3.1土料..............................................................................................................................41.3.2粘土料..........................................................................................................................41.3.3灌浆粘土料..................................................................................................................51.3.4块石及碎石料..............................................................................................................51.3.5砂料..............................................................................................................................52.调洪演算...................................................................................................................................62.1防洪标准确定.....................................................................................................................62.2基本数据.............................................................................................................................62.3泄洪建筑物方案拟定.........................................................................................................62.4水库各库容的确定.............................................................................................................72.5调洪演算.............................................................................................................................72.5.1宽顶堰堰流水力计算公式：.....................................................................................72.5.2试算法的基本原理.....................................................................................................82.5.3方案计算.........................................................................................................
