1、 I 摘 要 本项目位于江苏扬州境内，受地质构造、地层岩性、水文、气象等因素的综合影响， 地形起伏变化不大。路线区域内主要为丘陵区，冲沟较发育但规模较小，冲沟走向多与 路线相切割。区域内河流水系较发达。设计车速 100km/h。设计通过两个方案的比选来 确定较佳路线，两个路线全长大概都在三千五百米左右，所选方案二路线全长 3502.988m，双向四车道，路基宽 26m，路面宽 19.5m。所选沥青路面设计年限 15 年。 设计包括三个部分，内容如下：第一部分公路线形设计，在本部分，通过认真仔细 的研究，结合实际情况，综合考虑了路线填挖平衡、平曲线的优化、平曲线与竖曲线组 合原则等，确保了设计线
2、形的优化，然后根据两个比选方案的技术经济指标，对方案进 行比选， 从中确定较合理的方案第二方案作为推荐方案。 第二部分为路基工程设计， 包括支挡工程设计等。第三部分为路面工程设计，选择沥青混凝土路面和水泥混凝土路 面分别进行了设计，并对两个方案进行比选，选定沥青混凝土路面为推荐方案, 整个排 水系统由边沟、排水沟组成。相关的图纸、表格附后。 关键词： 路线平面线形； 纵断面设计； 横断面设计； 重力式挡土墙； 路面设计 II Abstract The design is the tenth contract section from Qachas to Mulberry Day in Jian
3、gsu, and the road is located in the Brahmaputra river basin . In the route region, there is mainly mountain ridge area, and the hypsography is series, so the design speed is 100km/h. The better route is determined through comparing of two program in the design. The length both are probably about 3，5
4、00 meters, and the selected program is 3502.988m, two two-way lanes, and the widen of the roadbed is 26m,19.5m of the pavement. Asphalt cement concrete pavement is designed for fifteen years. The design includes three parts, as follows : The road technical road linear design: In this part, through c
5、areful review, in light of the actual situation, the author considering the balance of excavation, the optimization of plane curve, the combination of plane curve and vertical curve, to ensure that the design of linear optimization. Then a more reasonable program - the second program are recommended
6、 through comparing the two program according to the technical economic indicator. The second part is the roadbed engineering design, which includ retaining engineering design and so on. Part three is pavement design, and the concrete pavement and asphalt cement concrete pavement both are considered and designed competely in the design, asphalt concrete pavement is recommended for the program, the whole drainage system is formed as side ditches, drainage ditch and pipe culvert.
