摘要

本设计研究的是郑州至民权开封段路段ZM-KF3标初步设计。主要研究方法是在考察现场地质水文资料，查阅当地交通量等信息的基础上，为郑州至民权两地间设计出一条交通便利，线形合理，经济美观，使用年限长久的高速公路。

河南省地处中国东部，路线所经地形为平原微丘区。本设计标段全线总长3087.094m。有 1个平曲线、6个竖曲线、3座高架桥，设计车速120km/h，路基宽度34.5m。路面为沥青混凝土结构。

本设计说明进行路线方案的论证，确定合适的设计方案，并推荐一个最佳方案进行详细的技术设计，包括路线的平、纵、横设计，路基路面设计和排水设计，等各方面内容。

关键词：高速公路，平、纵、横设计，路基，路面，排水

Abstract

The design and research of Zhengzhou Kaifeng road to civil rights ZM-KF3standard preliminary design. The main research methods was investigated in field geological and hydrological data, check out the local traffic information based on, for Zhengzhou to civil rights between two design a convenient transportation, linear rational, economic appearance, use fixed number of year long expressway.

Henan province is located in the eastern part of China, the routes through the terrain for the plain or hilly area. The design of full length3087.094m. There are 1horizontal curve vertical curve,6,3 viaducts, the design speed of120km / h, roadbed width34.5m. Pavement asphalt concrete structure.

The design of the route scheme argumentation, determine the appropriate design, and recommend an optimal scheme for the detailed design, including the flat, vertical, horizontal alignment design, design of roadbed and road surface and drainage design, and other aspects

Key words: highways, flat, vertical, horizontal design, subgrade, pavement, drainage
