道路工程毕业设计计算书

1/83摘要根据设计任务书提供的设计资料和设计要求以及交通部颁发的标准和规范对怀化至通道高速公路K176+500-K178+500段提供了路基路面综合设计。此次设计主要内容包括：路线设计、路基、路面设计，英文翻译，计算机程序编制。根据提供的路线原始资料，考虑土石方填挖平衡、最大纵坡、最小纵坡、坡长、高程控制点等因素进行纵断面设计,由此结合平面图进行横断面设计。根据设计段内的地形状况，设置了边沟、截水沟、排水沟、圆管涵等排水设施。同时，进行挡土墙设计计算和防护工程设计,设置挡土墙，采用植草皮等形式进行边坡防护。高填路堤路段采用修筑挡土墙的方法收缩坡脚，减少填方，增加路堤边坡稳定性；用毕肖普法进行了边坡稳定性验算。设计进行了沥青混凝土路面的设计和水泥混凝土路面的设计，由给定的交通量等条件，按照路面结构组合设计的原则，选用不同路面结构层厚度和材料进行结构设计验算。通过本次毕业设计，在专业知识方面得到了综合训练和提高，增强了独立分析问题和解决问题的能力。关键词：高速公路、路基设计、路面设计、综合设计ABSTRACT2/83Accordingtothedesigninformation,demandsofthedesigntaskinstrument,thetechnicalstandardsandspecificationsforhighwaydesignpublishedbytheMinistryofCommunicationsofChina,thecomprehensivedesignofhighwaysubgradeandpavementfromK178+500toK178+500hasbeencarriedoutbasedonthedataofHuaihua—TongdaoexpresswayinHuNanprovince.Ourprimecontentsofthedesignprojectincludeshighwayverticalalignment,thedesignofpavement,translatinganEnglisharticleintoChinese,andcompileasimplecomputerprogramme.Accordingtoroutefirsthandinformationthatisoffered,wemustonsiderthebalancebetweenthedigingoffillingout,heavyverticalslope,minimumverticalslope,thelongthofslope,highcontrolpoint,etc.Duringdesigningtheverticalsection,andcombinetheplanefigureanddesignthecrosssection.Accordingtotheconditionofclimatedistrictandremittingcalculationwaterofquantity,setupsideditch,interceptingditch,roundculverts,coverpullsculvertsetc.Meanwhile,doblockdesignofwallofsoilcalculateandprotectengineeringdesign,setuptheretainingwalltogoon,adoptplantturftoprotecttheslope,etc.Inhighembankmenthighwaysection,shrinkslopefootbybuildingtheretainingwall,reducethefilling,increasetheslopestability;makeuseofBISHOPtofollowthecheckingstabilitycalculation.Dothedesignwhichhascarriedonthepitchconcreteroadsurfaceanddesignofthecementconcreteroadsurfacebygivingvolumeoftrafficdefinitelyterms,accordingtothedesignprincipleoftheroadsurfacestructure,selectfordifferentroadsurfacestructurelayersofthicknessandmaterialthencarryonstructuraldesigncheckingcomputations.Throughthegraduationproject,thespecializedknowledgehasbeencomprehensivelyappliedandimprovedandtheabilitytoanalyseandsolveproblemsonourownhaibeenenhanced.Keyword：expressway;roadbeddesign;pavementdesign;integrateddesign；3/83目录第一章线形设计...................................................................................................................................61.1平曲线的计算...........................................................................................................................61.1.1平曲线要素的计算........................................................................................................61.1.2各主点桩号的计算........................................................................................................61.1.3逐桩坐标表...................................................................................................................71.2竖曲线的计算...........................................................................................................................91.2.1竖曲线要素的计算.......................................................................................................91.2.2竖曲线要点桩号及高程的计算...................................................................................9第二章路堤边坡稳定性分析............................................................................................................112.2计算分析................................................................................................................................13第三章挡土墙设计............................................................................................................................203.1设计资料................................................................................................................................203.1.1墙身构造......................................................................................................................203.1.2土壤地质情况..............................................................................................................213.1.3墙身材料......................................................................................................................213.1.4车辆荷载换算..............................................................................................................213.2墙背土压力计算....................................................................................................................213.2.1破裂面计算.................................................................................................................213.2.2验算破裂面是否交于荷载内.....................................................................................................223.2.3主动土压力计算.........................................................................................................223.2.4主动土作用点位置确定.............................................................................................223.3墙身截面性质计算........................................................................................................................223.3.1截面面积........................................................
