北华大学本科毕业设计摘要PAGE-36-PAGEI摘要本次毕业设计为湘潭某地区咸家町~彭家岭高速（100km/h）公路设计段，所经地区全境地势微丘，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；路面南湖学院本科毕业设计AbstractPAGEIIIAbstractThegraduationdesignforsaltyhometown~PengGulingxiangtanaregionhighway(100km/h)anddesignperiod.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南湖学院本科毕业设计目录PAGE-37-目录TOC\o"1-2"\h\z\uHYPERLINK\l"_Toc356114794"摘要PAGEREF_Toc356114794\hIHYPERLINK\l"_Toc356114795"AbstractPAGEREF_Toc356114795\hIIHYPERLINK\l"_Toc356114796"1绪论PAGEREF_Toc356114796\h-1-HYPERLINK\l"_Toc356114797"1.1课题背景PAGEREF_Toc356114797\h-1-HYPERLINK\l"_Toc356114798"1.2课题研究的目的PAGEREF_Toc356114798\h-1-HYPERLINK\l"_Toc356114799"1.3课题研究的意义PAGEREF_Toc356114799\h-1-HYPERLINK\l"_Toc3561
