公路改建为城市道路时横断面设计选择

Selection of Cross-sectional Design When Highway Reconstructed to Urban Road

随着城市经济的不断发展,由于承担的道路功能逐渐改变,部分连接城市中心与周边乡镇之间的公路改建为城市道路逐渐成为道路设计中一项发展趋势,而城市道路横断面设计是城市建设中的一项重要内容,针对公路改建城市道路中横断面设计的选择进行阐述,该思路对以后类似工程设计和建设有重要的指导意义。

With the continuous development of urban economy,it is a development trend that some highways connecting the city center and the surrounding towns are increasingly reconstructed to the urban roads in the road design because of the road functions to be changed,and the cross-sectional design of urban road is an important content in the city construction.The paper sets forth the selection of cross-sectional design in the reconstruction of highway to urban road.This idea has the great instructing significance for the design and construction of the future similar projects.
