道路毕业设计计算书

摘要I摘要本次毕业设计为佳木斯至牡丹江三级公路（A）标段，所经地区全境地势重丘，自东北向西南略呈倾斜。中部为山岭区。主要进行公路线形、路基和路面设计。其中，线形设计包括选线、方案比选、平面设计和纵断面设计；路基设计包括横断面设计、路基边坡设计等；路面设计包括路面结构层设计、路面结构层厚度设计和路面结构层验算。通过对当地交通量、地形、气候、水文、地质等状况的深入调查,确定了道路的等级以及道路设计的各个技术指标，为公路路线方案的比选准备了原始材料，确定了线路的平面位置。并且本设计对方案进一步细化，对路线的平面和纵断面进行了综合分析，根据技术标准及当地实际情况确定了路基宽度、高度及边坡坡度并且对路面材料、横断面布置、曲线超高及加宽的设置做了精心设计。关键词:线形；缓和曲线；竖曲线；路基；路面北华大学本科毕业设计IIAbstractThisgraduationdesignisthe(R)segmentofthesecondclassroadwhichstartsfromXinxiangtoTongling.Thissecondclassroadgoesthroughmountainregion.andmainlycarrysontheroadalignment,roadbedandpavementdesign.Then,alignmentdesignincludestochoosetheline,projecttocomparetochoose,theflatsurfacedesignandverticalsectiondesign.Theroadbeddesignincludesthecrosssectiondesignandtheroadbedsideslopedesignetc;Thepavementdesignincludespavementstructurelayerdesign,pavenentstructurelayerthicknessdesignandpavementstructurelayertochecktocalculate.Accordingtoinvestigatingthefurtherstateofthevolumeoftraffic,localtopography,climate,hydrology,geology,etc,thenconfirmstheclassofhighwayandtechnicalstandard,selectingtopreparethefirsthandmaterialofschemeofthehighway,andfixingthelevelofthecircuit.Furtherlyidesignthedetailsandhaveanalysisofthecircuitandverticalsection.Accordtothetechnicalstandardandlocalactualconditionsconfirmethewidthofroadbed,cutbank,material,crosssectionassign,curvesuperelevationandestablishmentthatwidendesignmeticulouslytoroadsurfacehighly.Keywords:alignment;easementcurve;verticalcurve;roadbed;pavement目录III目录摘要.....................................................................................................................................IAbstract..................................................................................................................................II1绪论.....................................................................................................................................11.1课题背景............................................................................................................................11.2课题研究的目的................................................................................................................11.3课题研究的意义................................................................................................................12太仓市滨江滨江二级公路设计总说明..............................................................................32.1基础资料............................................................................................................................32.2设计原始数据....................................................................................................................32.3设计依据............................................................................................................................32.4技术标准............................................................................................................................43线形设计..............................................................................................................................5选线步骤..................................................................................................................................54平面设计..............................................................................................................................64.1平面线形设计...................................................................................................................64.1.1线形................................................................................................................................64.1.2带缓和曲线的圆曲线计算.............................................................................................85纵断面设计........................................................................................................................185.1道路纵断面设计..............................................................................................................185.2道路纵断面设计原则.....................................................................................................185.3标高控制点的确定.........................................................................................................185.4纵断面线形方案的确定.................................................................................................195.6平纵组合设计.................................................................................................................226横断面设计........................................................................................................................236.1横断面设计.....................................................................................................................236.1.1断面设计原则...............................................................................................................236.1.2各项技术指标...............................................................................................................236.2平曲线加宽以其过度......................................................................................................236.3超高计算.......
