Preface
With the rapid development of China’s economy, the scale and variety of construction projects are expanding day by day, showing the momentum of vigorous development. Construction has become the most dynamic industry today. Road and bridge planning and design is the key to road and bridge construction. Its planning and design quality not only affects whether the functions of urban road and bridge meet the needs of urban traffic, but also affects the long-term planning of the city, the investment size of infrastructure and the future development prospects.
Bridges and roads bring great convenience to urban construction, promote economic development and social exchanges, and bring more convenience to the public. With the development of national economy, the scale of the city is expanding, the population of the city is increasing rapidly, and the traffic congestion problem is becoming more and more serious. As a means of transportation, road, bridge and tunnel have developed rapidly with their incomparable advantages, playing an increasingly important role in the development of urban economy.

前 言
随着我国经济的快速发展，建设工程的规模日益扩大，种类日益繁多，呈现出蓬勃发展的势头，建设已成为当今最具有活力的一个行业。道路桥梁规划与设计是路桥建设的关键，其规划设计质量不仅影响城市道路桥梁的功能是否满足城市交通的需要，而且还能影响城市的长远规划、 基础设施的投资大小和今后发展前景。
桥梁道路给城市建设带来了很大的便利，促进了经济发展和社会交流，为公众带来了更多的便利。随着国民经济的发展，城市规模在不断扩大，城市人口急剧增加，随之出现的交通拥堵问题日趋严重。道路桥梁隧道作为交通运输方式以其不可比拟的优势快速发展起来，在城市经济发展中发挥着越来越大的作用。
