河南汝阳至洛阳一级公路第4标段施工图设计
摘要
本次设计为河南汝阳到洛阳山岭重丘区一级公路常规设计。其目的是通过本次设计，为我们在如何进行公路施工图设计方面提供一次全面的、系统的训练机会，对公路施工图设计所包括的工作内容和工作程序有所了解，为今后从事公路工程设计、施工工作打下良好的基础。
设计部分的公路全长3000m，设计车速80km/h，双向4车道，设置中央分隔带。首先对交通量进行分析，查找相应技术规范，确定公路的等级以及设计需要的各种参数；然后在1：2000地形图上确定两条路线方案，结合沿线自然条件与主要技术指标的应用，进行路线方案论证与比选，从中选择最佳的设计方案并进行详细技术设计，内容包括：路线的平、纵、横设计，排水设计和挡土墙设计，及路面结构设计。最后完成施工图设计阶段应完成的各种图、表及设计说明书。

Construction Drawing Design of the 4nd Contract Section of Ruyang-Luoyang in Henna First Class Highway
Abstract
This is construction drawing design of the 4nd contract section of ruyang-luoyang mountainous heavy hilly area in Henna first class highway.Its purpose is to provide us a comprehensive and systematic training obout how to design of highway construction through the design,to understand the work contents and procedure of highway construction design , making a good foundation for highway engineering design and construction work in the future.
In this design the highway length is 3000m,the car speed is 80km/h , bi directional and four lane and setting Central Separate Belt. Firstly analysis the traffic conditines,to find the corresponding technical specifications, ascertain the level of highway design and various parameters what we need ;secondly ascertain two Route schemes at 1:2000 topographic map, combined with the application of natural condition and main technical indices , make route project argumetntation and selection, select the optimal design and make detailed technical design, contents include: the flat, the longitudinal and the lateral design ,the route rrainage design, retaining wall design and pavement structure design.Finally complete various chart and design manuals construction which we should finish in design stage.
Key Words: first class highway; horizontal curve; vertical curve; drainage; subgrade; retaining wall; asphalt pavement;
