摘要
福宜高速公路昆明城区段作为主城至呈贡新区“两快五主”联系通道的重要快速通道,大致呈东南走向,全长约53 km。昆明城区段主要采用主线高架加地面辅路的敷设方式,考虑到城市路网规划、现状道路情况、地下管线、现状高速公路、既有铁路、征地拆迁及沿线景观需求等因素,对道路沿线进行了分段精细化设计。首先,通过项目交通流量分析来准确把握技术标准及工程规模;然后,在满足既定功能需求的前提下设置不同道路横断面;最后,对跨越南绕城高速、子君山生态园和既有米轨等进行了关键节点的方案设计。
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.
