精品文档---下载后可任意编辑ABSTRACTThe total length of Dandong-Zhuanghe express highway EF sectionis km.The area which the road crosses is rolling terrain.And a technical standardof double-way four-lainhighway is adoptedin the design. The design speed is 100km/h.The width of the subgrade is 30 meters.The basic type of horizontal curve is adopted in this design for all the 4 horizontal curves and its minimum radius is 800m. Two vertical curves are designed and its minimum radius is 10000m and 10000m for convex vertical curve and concave vertical curve respectly.The minimum longitudinal grade is % which meet the drainage. All of the adopted technical standard can meet the highway with the second-class service level. 4 bridges are designed, which are medium bridge and small bridge respctively and 2 pipe culvert are also desinged.Different kind of drainage facilities are used in the drainage design. Gravity retaining wall and vegetation protection are used for the slope protection. The asphalt pavement is used in this highway. The concept of environmental protection is carried through in all the design to make the highway consistent with the nature. Different kinds of professional software are used to optimum the design result. The construction document is completed by AUTOCADand HintCADKeywords: express highway；construction document；asphalt pavement；prestressed hollow slab bridge; bridge; protection of side slope目录第一章绪论 1.1 道路线形，交通量情况概述 本次设计的道路运输的特点 沿线自然条件 气候特点 地形与地貌 地质与土质 植被覆盖与作物等情况 第二章公路技术等级的确定 2.1 概述 公路等级的确定 2.3 方案比选 第三章公路选线确定 选线原则 选线的具体做法 初步定线 3.2.2 具体定线 路线特点 第四章公路平面线形设计 4.1 概述 4.2 平面线形设计原则 4....
