内蒙古科技大学 本科生毕业设计说明书 题 目：湖北宜昌某公路新建工程设计 学生姓名： 学 号： 专 业：交通工程 班 级： 指导教师：讲师 湖北宜昌某公路新建工程设计 摘 要 本设计主要完成了湖北省宜昌某地区新建二级公路的设计，,以及该路段的地质、地形、地物、水文等自然条件,依据《公路工程技术标准》、《公路路线设计规范》等交通部颁发的相关技术指标,设计路线、路基、路面，以及涵洞、土石方调配、路基排水防护，交通安全设施等内容度为60km/h的双向行车道二级公路，路线全长3666.11米，路基宽度为10米，共设有5个平曲线，5个竖曲线。 路线部分包括平面、纵断面及横断面的设计。首先进行了纸上定线及修正导向线绘制，经比选确定最优方案；其次，根据平面结合当地的地形、气候、环境因素进行了纵断面设计；最后选定1km进行横断面设计，并绘制横断面图，计算土石方。路基设计中考虑超高和加宽计算，并进行了排水防护设计。根据交通组成及发展趋势结合当地筑路建材情况进行路面结构设计，经综合考虑对全线确定了防护及排水工程的结构尺寸、类型、位置，沿线涵洞进行了初步结构设计，以及基本的交通安全设施。公路工程造价设计中综合考虑施工，进行了初步的概算，造价总金额为4056408元。 ,设计了路基、路面、小桥涵等内容,由此圆满完成了江西赣州某新建二级公路初步设计。 关键词：新建二级公路；路线设计；路基设计；路面设计；排水设计；公路工程造价 New Construction of a highway in Yichang Hubei Design Abstract The design is mainly carried out in an area of Yichang new secondary road design, according to the information given by the analysis of the raw data, as well as the section of the geology, topography, terrain, hydrology and other natural conditions, according to the Highway Engineering technical standards , highway route design issued by the Ministry and other traffic-related technical indicators, designed to route, roadbed, road and culvert, earthwork allocation, subgrade drainage protection, traffic safety facilities and other content-based way. Vision will route traffic based on a design speed of design 60km / h lane two-way roads, the route length of 3666.11 meters, roadbed width of 10 meters, a total of five horizontal curve, five vertical curve. Section of the route, including plan, profile and cross-sectional design. First carried out on paper alignment and correction-oriented line drawing, by comparison to determine the optimal solution; Secondly, according to plane combines local topography, climate, environmental factors were longitudinal design; finally selected 1km conduct cross-sectional design and draw cross-sectional diagram, calculate the earthwork. Subgrade superelevation and widening considered in the design calculations and design for the drainage protection. According
