摘 要
本次设计为高速公路综合设计路段，此路段位于烟台境内，根据设计公路的交通量、地形特征以及使用任务和性质，确定公路等级为高速公路。在此基础上，结合沿线自然条件与主要技术指标，进行路线方案论证与比选，最终确定一个最佳方案进行详细技术设计。其主要内容包括：路线的平、纵、横设计，路基、路面设计和排水设计以及交通设施设计, 并完成施工图设计阶段应完成的各种图、表及设计说明书。本设计严格依据规范的各项指标进行，最后确定本高速公路设计速度为100km/h，路基宽26m，双向四车道，路线全长3478.085m，路面为沥青混凝土面层，厚18cm，全线共设计了2个平曲线、3个竖曲线、1条隧道、6个钢筋混凝土通道。

Abstract
This express section is located at the east of Chongqing province，which is heavy highland area．According to the requirements of mountain highway design, the grading of express is based on the traffic volume, the use of task and nature. Then, through combining natural conditions along and the main technical indicators, evaluating and electing the route, this express section ultimately determine the best option for a detailed technical design. Its main contents include: plane design, vertical curve design, transect curve design, roadbed design, road surface design, drainage design and traffic facilities design. In addition, all kinds of the figures, tables, and specifications are given in detail in this paper. After conducting technical feasibility studies accord to specification, the designing velocity is 100 km / h. The width of the roadbed is 26 meters with four two-way lanes. The length of the road is 3456.247meters. The road’s surface is paved by asphalt concrete. There are two plane curves, two vertical curves, a total of two bridges, five reinforced concrete channel.
