道路桥梁毕业设计

沈阳建筑大学城市建设学院毕业设计（论文）1摘要根据设计任务书提供的设计资料和设计要求以及部颁标准和规范，对泰和至凤凰二级公路综合设计K0+000～K5+495.719段进行了路基路面综合设计，设计车速为60km/h，双向两车道。主要内容包括：路线平面设计、路线纵断面设计、路基横断面设计、路基路面排水设计、路面结构设计、小桥设计等。在平面设计中，考虑到是平原微丘区新建二级公路，在设计线路上选了五个交点，曲线半径分别为800m,400m,700m,700m,400m对平面交点进行了校核。在纵断面设计中，全线共设六个变坡点，竖曲线半径分别为36000m，2000m，5000m，4200m，18000m并且进行了竖曲线要素计算。在横断面设计中，在圆曲线半径小于不设超高的最小半径（1500m）的平曲线处还进行了超高的计算,进行了土石方计算和调配。在排水设计中，选择一公里典型路段，设置了截水沟、排水沟，并且在高路堤处设置为散排水形式。在小桥涵设计中，设计内容是一座跨径为12m的装配式钢筋混凝土空心简支板桥，主要进行了桥梁上部结构的计算、配筋和验算，包括主梁计算橡胶支座计算。本次毕业设计是一个总结也是一个锻炼，通过设计，在专业知识方面得到了综合训练和提高，增强了独立分析和解决问题的能力，掌握了利用理论知识解决实际问题的方法，取得了很好的效果，为以后的工作奠定了一个良好的基础。关键词：二级公路；路线；路面；桥梁；综合设计沈阳建筑大学城市建设学院毕业设计（论文）2AbstractAccordingtothedesigndataanddesignrequirementsprovidedwiththedesignplandescriptionsandCarestandardsandnorms,TaihetoFenhuangTownsecond-classhighwayK0+000~K5+495.719sectionontheroadbedcomprehensivedesign.Thedesignedvehiclespeedis60km/h,two-waytwolanes.Themaincontentsareroutegraphicdesign,longitudinaldesignroute,routecross-sectionaldesign,pavementstructuredesign,roadbeddrainagedesign，bridgedesign,etc.Ingraphicdesign,consideringitisthehighlevelofroadsintheplainarea,thecircuitonthefourintersectioncurveradius,respectivelyfor800m,400m,700m,700m,400mcheckstheintersectionoftheplane.Inthedesignofallcubes,consistsoffivechangingslopepoint,verticalcurverespectivelyfor36000m，radiusof2000m，5000m，4200m，18000mandthecurveelementscalculation.Inthecross-sectionaldesign,incircularcurveradius,lessthantheminimumradiuswhichdonotsethighintheflatcurve(1500m)wastheultrahighcalculation,theearthworkcalculationandallocate.Inthedrainagedesign,thechoiceofatypicalsections,setthekmcutditch,drainage,andhighembankmentinasettingfordrainageformscattered.Inthesmallbridgedesign,designcontentisaspanof12mofthePrefabricatedreinforcedconcretesimplysupportedhollowslabbridge,themainbridgeoftheupperstructurecalculation,reinforcementandchecking,includingthemaingirdercalculationandcarriagewaycalculation.Thegraduationdesignisasummaryalsoanexercise,throughthedesignintheprofessionalknowledge,weimprovethecomprehensivetraininggot,enhancetheindependentanalysisandtheabilitytosolveproblems,andmastertheuseoftheoreticalknowledgeofmethodstosolvepracticalproblems,andgoodresultshavebeenachieved,laidagoodfoundationforthelaterwork.Keywords:Secondclassroad;Line;Pavement;Bridge;Comprehensivedesig沈阳建筑大学城市建设学院毕业设计（论文）目录第一章前言..............................................................11.1公路建设的意义.......................................................11.2.1气候特点...........................................................11.2.2地质地貌...........................................................1第二章路线设计和计算...................................................42.1选线.................................................................42.1.1平原微丘地区选线原则...............................................42.1.2线形与技术标准.....................................................42.1.3以平面为主安排路线.................................................42.1.4处理好与农业的关系.................................................42.1.5路线与城镇的联系...................................................52.2.2二级公路的主要技术指标.............................................72.2.3带有缓和曲线的平曲线计算公式.......................................72.2.4路线曲线要素计算...................................................83.1纵断面设计方法与原则................................................133.2平纵线形的协调......................................................143.3竖曲线计算..........................................................143.3.1简述..............................................................143.3.2竖曲线要素的计算公式..............................................143.3.3竖曲线设计........................................................15第四章路线横断面设计...................................................174.1横断面的组成.........................................................174.4横坡的确定..........................................................184.4.1路拱坡度..........................................................184.4.2路肩坡度..........................................................184.4.3超高及超高缓和段..................................................194.4.4加宽..............................................................20沈阳建筑大学城市建设学院毕业设计（论文）4.5土石方数量计算与土石方调............................................214.5.1横断面面积的计算..................................................214.5.2路基土石方工程数量的计算..........................................214.5.3土石方调配........................................................22第五章路基路面排水设计.................................................245.1路基路面排水的一般原则...............................................245.2路面排水设施........................................................245.2.1边沟..............................................................245.2.2截水沟.............................................................265.2.3排水沟............................................................265.2.4急流槽............................................................27第六章路面结构设计和计算...............................................286.1设计说明............................................................286.1.1路面等级......
