2、进行排水，保证路基路面的稳定性；最后进 行了路面结构的组合设计等内容。 整个设计计算了路线的平、纵曲线要素，设计了路基、路面、桥涵等内容，圆满 完成了罗埠至蒋堂段一级公路综合设计。 关键词： 平面设计 纵断面设计 横断面设计 排水设计 路面结构设计 毕业设计（论文） 第 2 页 共 47 页 装 订 线 ABSTRACT This paper mainly introduces the design process of a section of LuoBu to JiangTang arterial highway. Based on the information given by the
3、 analysis of the raw data， and the section of geology， topography， terrain， hydrology and other natural conditions， according to “Highway Engineering Technical Standard“， “Road Design Standards“ issued by the Ministry of Communications and other related technologies indicators， I have finished this
4、task under the teachers guidance. The area that this highway passes through belongs to plain with plain and hilly area. According to the traffic volume in the future， I design this highway into design speed of 100Km/h with bi-directional four-lane arterial highway， with route length of 5109.975 mete
5、rs， embanKment width of 26 meters， 3 horizontal curves， and 5 vertical curves. Line design including graphic design， longitudinal design and cross-sectional design; Then I accomplished the pavement drainage design， which uses ditches and drains for drainage to ensure the water stability of roadbed a
6、nd pavement; at last， a composite design of pavement structure and other designs are also finished. The whole design have calculated the planar and vertical curve elements of this line， besides roadbed， pavement， bridges and so on. Complete the comprehensive design of the section of LuoBu to JiangTang arterial highway successfully. Key words: Grap
