引言中国的交通贯穿东西南北，是连接各地国民经济的纽带，是国民经济的大动脉。交通运输是一个国家繁荣重要的物质基础物质，财富生产和分配过程中，交通运输在在广大人民的生活中起到极为重要的作用。与其它运输方式相比，公路运输具有灵活性较高的优点，尤其是在高速公路建设方面，再加上现代计算机技术正在飞速发展，公路运输网络逐渐完善，这也是促进公路运输发展的一大助力。也正是公路运输运量灵活可变，选择性较高，服务水平也就容易得到保障。42490
改革开放以来，我国的公路交通发生了历史性的巨变，公路的建设规模迅速增长，高速公路的快速发展，农村公路也在稳步发展，隧道的建设也是闻名全球，科技创新也是实现跨越式发展。这也说明了交通运输在国内经济增长过程中的重要性。国内公路运输服务的方式，还有营业主体慢慢有了多样化的趋势。论文网
本篇设计为临安线一级公路设计，主要涵盖了道路的平面设计，纵断面设计，横断面设计，路基的设计（包括路基稳定性分析以及挡土墙的设计与布置），沥青路面和水泥路面的设计，最后还有涵洞的设计。期间，还有对EICAD使用的要求，用EICAD完成了对道路“平纵横”的设计出图，不得不说，这是一个很好的软件，以前都是手算，很繁琐，有了这个软件，给我们省下了很多时间。
abstract
China traffic through the four corners of the world, is the connecting link around the national economy, is the main artery of national economy. Transportation is an important material base of national prosperity, the process of the production and distribution of wealth, transportation plays a very important role in the lives of the majority of people. Compared with other modes of transportation, highway transportation has the advantages of high flexibility, especially in highway construction, coupled with the modern computer technology is the rapid development, the highway transportation network gradually improve, this is to promote a major impetus for the development of road transport. Also is the road transport volume flexible variable, high selectivity, the level of service is also easy to be guaranteed.
Since the reform and opening up, China's highway traffic occurred historic change, the rapid growth of the scale of highway construction, the rapid development of highway, rural road also in steady development and construction of the tunnel is known around the world, science and technology innovation is to achieve development by leaps and bounds. This also shows the importance of transportation in the process of economic growth in china. Domestic road transport services, as there are a variety of business subjects slowly have a variety of trends.
This design for Lin'an line highway design, which mainly covers the road plane design, vertical section design, cross section design, roadbed design (including roadbed stability analysis and retaining wall design and layout) and the design of asphalt pavement and cement concrete pavement, and finally the culvert design. Period, and the use of EICAD requirements, EICAD completed the on flat road aspect of design drawing, have to say, this is a very good software, before is the hand, very cumbersome, with the software, give us a lot of time.
