青岛理工大学毕业设计（论文）Abstract青岛理工大学毕业设计（论文）摘要摘要本设计为一段山岭区二级公路常规设计，起点高程180米，终点高程150米，地势较为平坦。拟建公路路段为K0+000至K2+371.191段，全长2371.191米，采用双向两车道形式，无中央分隔带，设计时速为60km/h，路面结构采用沥青路面。整个排水系统由边沟、排水沟组成。挡土墙采用重力式挡土墙。本设计分为初步设计和详细设计两个阶段。初步设计中，首先根据交通量确定道路等级，然后在1:5000地形图上确定两条备选路线，对所定路线进行方案比选，从中选择最佳方案。详细设计从确定方案中进行平面设计，纵断面设计，横断面设计，前期工作较初步设计更具体化，此外还对路基，路面，排水，进行了详细设计。通过这次设计不但了解建设公路的各个步骤，而且也能熟练的运用AUTOCAD进行制图。关键词：路线设计，纵断面设计，平面设计，横断面设计ABSTRACTThisdesignisaboutaroadofsecondgradinthehillyarea.Theelevationofthestartpointis180m,theelevationoftheendis150m.Topographyareflat.Thetotallengthoftheproposedhighwayis2371.191m,itisatwo-lanetwo-wayroad,designingspeedis60km/h.Thisdesignismadeupofprimarydesignanddetaileddesign.Intheprimarydesignprocess,firstofall,weshoulddeterminetheroad-gradeaccordingtothetrafficvolume,then,twospareroutesaredeterminedintheterrainmapwithascaleof1:5000,includingtheplanedesign,theverticalsectiondesign,thetransectdesign，thesettingofthebridgesandculverts.Atlast,thereisacomparebetweenthetwoprojectsandthebetterwillbeadopted.Inthedetaileddesignprocess,horizontaldesign,verticaldesignandthecross-sectionaldesignwillbeconductedfromthedeterminedprogram.Theprimetaskismoreconcretelythantheprimarydesign.Furthermore,thesubgradeandpavementhavebeendesignedinstressaswell.Thisdesignnotonlycanmakeusunderstandtheeachstepofconstructioninbuildingroads,andcanalsomakeususeAUTOCADfordrawingskilled.KEYWORDS:routeselection,verticaldesign,horizontaldesign,cross-sectionaldesign青岛理工大学毕业设计（论文）前言目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc327952852"摘要PAGEREF_Toc327952852\hIHYPERLINK\l"_Toc327952853"ABSTRACTPAGEREF_Toc327952853\hIIHYPERLINK\l"_Toc327952854"前言PAGEREF_Toc327952854\h1HYPERLINK\l"_Toc327952855"1绪论PAGEREF_Toc327952855\h2HYPERLINK\l"_Toc327952856"1.1选题背景PAGEREF_Toc327952856\h2HYPERLINK\l"_Toc327952857"1.1.1我国公路现状PAGEREF_Toc327952857\h2HYPERLINK\l"_Toc327952858"1.1.2我国公路发展规划PAGEREF_Toc327952858\h3HYPERLINK\l"_Toc327952859"1.2本设计的基本情况PAGE
