交通工程专业-毕业设计 计算说明书

苏州科技学院本科生毕业设计（论文）1毕业设计说明书刘家湾至罗家院子公路工程施工图设计摘要本设计为刘家湾至罗家院子公路工程施工图设计，分为初步设计和详细设计两个步骤。初步设计阶段：先根据现状的交通量资料，预测设计年交通量，并确定确定道路等级；然后在1:10000地形图上确定两条备选路线，分别进行平面设计、纵断面设计、横断面设计以及拟定桥涵位置，最后从各个方面对所定两条路线进行比选，从中得出一个最佳方案。详细设计阶段：对确定方案（方案一）的7.015公里进行详细计，包括平面、纵断面、横断面设计的详细设计，路面结构设计，排水规划设计及涵洞设计，施工组织设计。关键词：二级公路；施工图设计；平、纵、横设计；路面结构设计、排水规划设计、涵洞设计、施工组织设计。苏州科技学院本科生毕业设计（论文）2HighwayDesignFromLiujiawantoLuojiayuanziAbstractTheconstructiondesignfortheliujiawantoluojiayuanziHighway，isdividedintotwosteps：preliminarydesignanddetaileddesign.Thepreliminarydesignstage:todetermineroadgradeaccordingtothestatusoftrafficdatabasedonpredicteddesignyeartrafficvolume;andtheninthe1:10000topographicmaptodeterminethetwoalternativeroutes,tomakethegraphicdesign,longitudinaldesign,bridgelocation.Thenselectabestsolutionbasedonthinkingoverthevariousaspectsofthetworoutesselection.Detaileddesignstage:determiningtheprogram(programA)of7.015kmfordetaileddesign,includingflat,profile,cross-sectionaldesignofthedetaileddesign.Andalsoincludingroaddesign,drainageplanningdesign,culvertdesignandconstructiondesign.Keywords:Secondaryroads;constructiondesign;flat,verticalandhorizontaldesign;pavementdesign,drainageplanninganddesign,culvertdesign,constructiondesign.苏州科技学院本科生毕业设计（论文）3目录第1章绪论...........................................................61.1道路所在地区概况......................................................61.2道路技术等级的确定....................................................71.3设计技术指标..........................................................7第2章方案比选.......................................................92.1选线和定线............................................................92.2方案比选表（表2-1）..................................................102.3方案比选结果.........................................................11第3章平面详细设计..................................................123.1平面线形设计.........................................................123.2平曲线设计计算.......................................................123.2.1路线转角、方位角的计算....................................................123.2.2平曲线要素计算............................................................143.2.3平曲线主点桩号计算及校核..................................................153.3设计成果.............................................................18第4章纵断面设计....................................................194.1纵断面设计步骤.......................................................194.1.1纵断面设计步骤............................................................194.2竖曲线设计...........................................................204.2.1纵坡设计..................................................................204.2.2竖曲线半径的选取..........................................................214.2.3竖曲线设计计算............................................................224.3设计成果.............................................................25第5章排水规划设计..................................................265.1沟渠设计.............................................................265.1.1边沟设计..................................................................265.1.2排水沟设计................................................................275.1.3截水沟设计................................................................27第6章横断面设计....................................................296.1横断面组成部分设计...................................................296.1.1横断面的组成及宽度........................................................296.1.2路拱设计..................................................................296.1.3边沟及排水沟设计..........................................................30苏州科技学院本科生毕业设计（论文）46.1.4边坡设计..................................................................306.2加宽设计和计算.......................................................316.2.1加宽设计..................................................................316.2.2加宽计算..................................................................316.3超高设计及计算.......................................................326.3.1是否设超高的判定：........................................................326.3.2超高过渡方式..............................................................336.3.3超高缓和段计算及检验......................................................336.3.4超高验算..................................................................356.4路基设计表...........................................................366.4.1横断面各点与设计高之差....................................................366.5土石方数量计算与调配.................................................396.5.1横断面面积计算............................................................396.5.2土石方数量计算............................................................396.5.3土石方的调配..............................................................40第7章路基路面设计..................................................437.1路基防护与加固工程设计...............................................437.1.1植物防护..................................................................437.1.2工程防护..................................................................447.2基础资料及路基类型的确定.............................................447.2.1自然条件及气象资料..........................
