Abstract:Kunming urban section in Fude-Yiliang Expressway is an important fast channel connecting the main city to two expressways and five trunk roads of Chenggong New District, which is generally southeastward. Its total length is about 53 km. The laying method of the elevated bridge in the main line plus the ground side road is mainly used for the urban section of Kunming City. By considering the factors of urban road network planning, current road conditions, underground pipelines, current expressways, existing railways, land acquisition and landscape demands along the line, the refined design is carried out for the roads along the line by sections. The technical standards and the engineering scale are accurately grasped through the analysis on the traffic flow of the project. Under the premise of meeting the established functional requirements, the different cross sections of roads are set. The schemes of key nodes crossing South Beltway, Zijunshan Ecological Park and the existing meter rails are designed.
