线按平原重丘区三级公路设计，路基宽 7.5m，设计车速30Km/h,采用 水泥混凝土路面，设计基准期为 20年。1.1.2沿线自然情况设计路段为平原重丘区，部分地区纵坡起伏较大，地表植被为稻田、 树林，间有水塘。沿线所出自然区划为IV3区，属东南湿热区，雨量充沛集中，台风暴雨多，水毁、冲刷、滑坡是道路的主要病害，该区 水稻田多，土基湿软，夏季炎热。全线地质条件良好，土壤为砂性土。1.2设计任务根据地形图上提供的起、终点位置和给定的公路等级进行选线、路基 路面的设计和施工组织设计。完成设计所要求的各种设计计算书、设 计图表和设计总说明。完成设计资料应达到并符合施工要求。1.3主要设计指标（1）公路等级：三级公路（2）设计速度：30km/h（3）采用水泥混凝土路面，设计年限 20年。（4）道路的使用性质和交通量：交通量年平均增长率为5%算知道设 计基准期内设计车道标准荷载累计作用次数为 280次/日，属于重交通 等级。（5）路线设计起始点及设计高程：起点桩号：kO+OOO设计高程：1343.333终点桩号：k3+118.626设计高程：1385.0411.4主要技术标准设计速度：30km/h的三级公路设计标准由？规范？查得，现列表如下表1.1主要设计标准规范标准三级公路设计速度（km/h）30路基宽度（m一般值7.50最小值车道宽度（m3路肩宽度（m右侧硬路肩一般值最小值土路肩一般值0.75最小值0.5圆曲线最小半径（m一般值65极限值30最大纵坡（）8最小坡长（m100最大坡长（m4%11005%9006%7007%5008%300竖曲线最小半径（m）凸形一般值400极限值250凹形一般值400极限值250竖曲线最小长度（m）25停车视距（m）30平面设计2.1设计原则在路线设计过程中应妥善考虑到远期与近期，整体与局部的关系结合地形、地址、水文、建筑材料等自然条件，同时对平、纵、横三 方面进行终合考虑，协调一致，使平面线形与纵面线形的组合满足汽 车动力性能的要求并充分考虑、驾驶员在视觉、心理方面的要求，保 持线形在视觉上的联系和心里的协调，同时注意与公路周围环境的配 合，并根据公路的使用任务、性质合理利用地形。选择线形在保证平、 纵、横设计“合理又合法”的原则下作到平面顺适、纵坡均衡、横面 合理，逐步实行标准化。2.2设计总要求221设计要点（1）路线起点除必须符合公路网规划要求外，对起终点前后一定长度 范围内必须作出按路线方按和近期实施的具体设计。（2）视觉良好，路线平、纵、横各组成部分空间充裕。（3）诱导视线各种设施所构成的视觉系统，应使驾驶者在是视觉上能 预知公路前进方向和路况变化，并能急时采取安全措施。(4) 线形流畅，景观协调，行车安全，舒适，使驾驶员在视觉上能预 知公路前方和路况的变化。222平面路线布设的原则和具体方法公路平面线形由直线、圆曲线和缓和曲线组成。直线应根据路线 所处的地形、地物、地貌并综合考虑驾驶者的视觉、心理状态等合理 布设。但是直线的最大长度应有所限制，应结合具体情况采取相应的 的技术措施。不论转角大小均应设置圆曲线，当不得已而设置小于7度的转角时则必须设置足够长的曲线，当圆曲线半径小于不设超高最 小半径时，应设超高，并且用超高缓和段连接。缓和曲线长度还应大 于超高过渡段的长度。超高的横坡度按公路等级、计算行车速度，圆 曲线半径，路面类型，自然条件和车辆组成等情况确定。一般公路圆 曲线应综合考虑设计原则，本段共设 15个圆曲线。2.3平曲线计算2.3.1确定交点本拟建公路属于山岭重丘区三级公路， 拟建路线全长3118.626米 本着经济美观的原则进行选线。 全线确定了
