It also plays important role in the production and distribution of goods, and in everyone’s life. Road transporting has many advantages when compared to other transporting ways. It will bring out huge economical advance when it was paved to certain area, especially those mountainous regions which always are poor and roadless. This thesis intends to design a construction plan for a second-class road .There is a warm, subtropical climate, four distinct seasons and warm in winter, and hot in summer. This design includes plane linear design, vertical section design, horizontal section design, roadbed design and so on. The plane linear design includes information compiling, lines drawing on paper, fix on requisites of curves; Vertical section design is comprised of road elevation, design elevation, depth of dig and fill and requisites for vertical curve; Contents of horizontal section design are fixing standard horizontal section, mapping every horizontal section; At last make a blueprint according to traffic information and road design rules; Keywords: Upright curve Vertical section Transect Roadbed Road surface structure 1设计总体说明 1.1 设计任务1.2任务要求 通过本设计要求能够综合运用专业所学的知识，根据有关的设计规范掌握各设计阶段的设计内容，掌握设计过程中设计原始资料的采集方法与内容，掌握路面设计参数的确定、选用及计算方法；掌握公路勘测设计的程序及方法，以达到熟练从事公路专业的工作能力。 1.3 建设意义 交通运输是国民经济的基础产业之一，是国民经济的大动脉，它把国民经济各领域和各地区联系起来，在社物质财富生产和分配过程中，在广大人民的生活中起着极为重要的作用。改革开放以来，随着社会主义商品经济和乡镇企业的兴起，尤其是近年来西部大开发战略的实施，加之现在的中部沦陷地区的崛起政策。公路运输已经显示出了其它交通方式所不能具有的巨大优势。“要想富，先修路”、“公路通，百业兴”反映了人们尤其是偏远山区人们的深切感受。 1.4 交通 设计交通资料如表1-1所示 黄河JN-150 49.00 101.60 1 双 250 解放CA10B 19.40 60.85 1 双 1600 跃进N
