摘要
本设计为湖南省长沙市黄桥大道二级公路K0+000~K3+011段初步设计,设计速度为60Km/h,采用双向二车道,整体式双幅路基断面形式,,行车道宽2×;桥涵汽车荷载为公路—Ⅱ级。
通过查阅《公路工程技术标准》(JTG B01-2003)、《路基设计规范》(JTG D30-2004)、《路基路面工程》以及《桥梁工程》等相关资料,本设计完成了以下4个方面的设计任务。路线设计:按照路线应尽量选择避免穿过不良地质地段、减少拆迁的原则,对线路进行了系统的比选和优化设计;路基设计:本路段路堤挡土墙采用重力式挡土墙,并选取地势较不利地段进行了挡土墙稳定性验算;排水工程设计:本路段共设置了1座箱涵,4座圆管涵,设置了边沟、排水沟等,力求保持原有水系及排灌系统,以利农田基本建设,保持生态平衡,力求采用标准、轻巧、经济的结构物;路面工程设计:对沥青路面与水泥混凝土路面分别进行了设计与综合比较。

ABSTRACT
This design is the preliminary design of the secondary highway of Huangqiao Avenue K0+000~K3+011 segment in Changsha City ,Hunan Province, the design speeds of 60Km/h, using two-way two lane,integral twin cross-section type of subgrade, roadbed width of , lane width of 2×; culvert car load for the road - Ⅱ grade .
Referring to “Highway Engineering Technical Standard”(JTG B01-2003),“Roadbed Design Specifications”(JTG D30-2004), “Roadbed Pavement Engineering”,“Bridge Project”and several other relative information, the design pleted with four following aspects of design tasks. Route Design:on the principle of route selection,the route should avoid acrossing adverse geological location and reduce demolition,the design conducted system selection and optimization design; Roadbed Design: the road embankment retaining wall using gravity retaining wall ,and choosing the unfavorable terrain to checking the stability of retaining walls;Drainage Engineering Design:this section were set up a culvert,four pipe culvert ,ditches and drains,strive to maintain the original water and irrigation system to facilitate farmland capital construction, keeping ecological balance,and strive to adopt a standard,deft,economical structure;Pavement Engineering Design:respectively designed pared the asphalt pavement and cement concrete pavement.
