第9页共32页重庆交通大学毕业设计(论文)题目：重庆地区某新建二级公路设计起始桩号：K0+000～K2+212.567学生姓名学院名称专业名称指导教师年月日第I页共32页更多资料参见我的新浪博客：或联系QQ：734123896摘要为了巩固我们所学的知识，并在各方面得到更进一步的提高，我们选择了重庆某地区新建二级公路设计作为毕业设计，这是在毕业之前对自身学习状况的最后一次检查。我所选择的设计路段是从K0+000至K2+212.567段，全长2212.567米，设计车速60km/h,路基宽度为10m。此次毕业设计主要包括的内容如下：1、路线设计：在已知平面图的情况下，进行纵断面的设计，要求线路顺畅、填挖平衡、经济合理。2、路基设计：包括各个桩号的填挖计算、填挖较大地段的稳定分析、整个线路的土石调运借配等。3、路面设计：路基在不同干湿状态下，所设计的沥青路面和水泥混凝土路面方案的比选，要求经济合理，便于施工并满足各设计规范要求。4、路基、路面排水工程；高填挖地段的防护工程以及路基加固工程：这一部分相当重要，对于路基排水，采用了边沟、截水沟、急流槽等排水设施；对于路面排水，除了对路面进行了路拱设计，还进行中央分隔带的排水设计；对于特殊路段的防护和加固主要采用了骨架内植草和挡土墙。5、桥涵设计：包括桥梁和涵洞的形式、尺寸的设计。6、英文翻译7、专题研究：对此行业新观点或者新技术的综述。关键词：路线；路基路面；桥涵；综合设计第II页共32页更多资料参见我的新浪博客：或联系QQ：734123896AbstractThedesignisveryimportanttous.Notonlybecausethisisourlastassignmentbeforegraduation,butalsoitcanenhanceourability.Inthisdesign,ourtaskistodesignansecondaryroad.Theroad,whichis2212.567mfromK0+000toK2+212.567.Thedesignspeedis60km/handthewideofthesubgradeis10m.Ourprimecontentsofthedesignprojectincludes:(1)Makesuretheverticalsectioninconditiononthelandformwhichisknown.(2)Thedesignofthesubgrade,andtheworkinvolvesalotofitems:analyzethestabilityofbrae;thefillordigheightofeverypegandsoon.(3)Thedesignofpavement,andthiscontentsthattheselectoftheconstructionaboutconcreteandasphaltpavementindifferentcase.(4)Thedesignofthedrainageproject,protectiveproject,subgradereinforcedproject,andtheseareveryimportanttothewholework.(5)Thedesignofthebridgeandculvertswhichincludesizeandform.(6)TranslateanEnglisharticleintoChinese.(7)Investigatethemonographwhichaboutanewtechniqueoranewviewpointinthisfield.Keywords：wayroadbedroadsurfacebridgeculvert第I页共32页更多资料参见我的新浪博客：或联系QQ：734123896目录1路线设计.....................................................................................................................................11.1线形设计一般原则..............................................................................................................11.2平面线形要素的组合类型..................................................................................................11.3平面设计方法......................................................................................................................11.4平曲线设计..........................................................................................................................21.4.1平曲线要素计算...........................................................................................................21.4.2逐桩坐标计算...............................................................................................................41.5纵断面设计..........................................................................................................................41.5.1竖曲线设计...................................................................................................................41.6横断面设计..........................................................................................................................51.6.1路基宽度的确定...........................................................................................................61.6.2路堤和路堑边坡坡度的确定.......................................................................................61.6.3超高与加宽...................................................................................................................62路基路面设计.............................................................................................................................72.1一般路基设计......................................................................................................................72.1.1路基的类型和构造.......................................................................................................72.1.2设计依据.......................................................................................................................72.1.3路基填土与压实...........................................................................................................72.2软基处理..............................................................................................................................82.3路基防护..............................................................................................................................92.4支挡结构设计......................................................................................................................92.5路面结构设计....................................................................................................................112.5.1.路面结构组成...........................................................................................................112.5.2路面类型.....................................................................................................................112.5.3沥青路面设计.............................................................................................................122.5.4水泥路面设计....................................................................
