公路施工图设计摘要本毕业设计为公路施工图设计。福白公路起于福田寺，止于白螺，是一条平原区二级公路，双向两车道，设计时速60km/h，设计里程约7.1km。本毕业设计要求基于实测地形图以及相关的补充资料，根据道路勘测设计基本原则以及路基路面工程基本理论，综合考虑当地的技术和经济条件，严格按照施工图设计过程进行独立作业，主要包括路线设计、路面结构设计以及路基处理方案设计，各项技术指标均要满足相关规范的要求。本设计运用纬地5.88道路设计软件进行道路路线设计。本设计标段全线总长7304.526m。该路线包含3个平曲线，最大半径340m，最小半径270m；9个竖曲线,最大半径18200m，最小半径12600m；1座沿途构造物桥梁。路基宽度10m（土路肩0.75m×2，硬路肩0.75m×2，行车道3.5m×2），双向两车道。不设超高路段的行车道及硬路肩路拱横坡采用2.0%，土路肩路拱横坡3.0%。设计填方总量35782m3，挖方总量36530m3，填挖基本平衡，且路基稳定性好，不需设置挡土墙，主要采用植物防护。本设计运用HPDS路面设计软件进行路面结构设计。路面材料采用沥青混凝土结构选用沥青混凝土材料。路面上面层采用4cm厚的细粒式沥青混凝土AC-13，下面层采用6cm厚的中粒式沥青混凝土AC-20，基层采用20cm厚的水泥稳定碎石，垫层采用20cm厚的水泥粉煤灰碎石。关键词：施工图设计；平原区二级公路；路面结构设计；纵断面设计；横断面设计；沥青路面设计1TheconstructiondrawingdesignoftheFuBaisecond-classhighwayABSTRACTThegraduationdesignistheconstructiondiagramdesignofFuBaisecond-classhighway.ItconnectsFutiansiandBailuo,whichislocatedinplains.Itisatwo-lane,two-wayroad,andthedesignspeedofroadis60km/h.Thelineofdesignlengthisabout7.1km.Thegraduationthesisasksformeasuredtopographicmap,itisonthebasisofthetheoryofRoadSurveyandDesignandSubgradeandPavementEngineering.Itneedstosyntheticallyconsiderthelocaltechnologyandeconomicconditions.Tohaveaindependentoperationsinstrictaccordancewithconstructiondrawingdesignprocess.Mainincludingalignmentdesign,pavementstructuredesignandsubgradedesign.Allindexshouldmeettherequirementsoftherelevantspecification.The5.88roaddesignsoftwareisappliedforroadroutedesign.Thelineofdesignlengthis7304.526m,containing3planecurves,whichmaximumradiusis340metersandtheminimumradiusis270meters.And9verticalcurves,whichmaximumradiusis18200metersandtheminimumradiusis12600meters.Roadbedwidthis10m(earthshoulderis0.75m×2,hardshoulderis0.75m×2,carriagewayis3.5m×2),andfreewayistwolanes.Thenosuperelevationsectionsweredesignedandhardshoulder’crownslopeis2%,earthshoulder’crownslopeis3%.Designedtofillthetotalsquareis35264m3,theexcavationtotalsquareis39229m3.Fillinganddiggingremainingbalanced.Subgradeisverystable,anditisunnecessarytosetretainingwallsanduseplantprotectionmeasures.HPDSpavementdesignsoftwareisappliedforroadstructuredesign.Thepavementmaterialiswithasphaltconcretestructure,selectionofasphaltconcretematerial.Thetoplayerwiththicknessof4cmfinegrainedasphaltconcreteAC-13,thefollowinglayeradopts6cmgraintypeasphaltconcreteAC-20.Pavementismadeof20cmcementstabilizedmacadam,andcushionismadeof20cmcementflying-ashgravelpile.Keywords：constructiondrawingdesign;second-classhighwaylocatedinplains;pavementstructuredesign;verticalsectiondesign;crosssectiondesign;asphaltpavementdesign2目录1绪论........................................................................................................................................................-6-1.1概述..............................................................................................................................................-6-1.2...
