摘要
城市立交节点方案的确定是一个多层次分析、多目标决策、多因素制约的选择过程。介绍了工程背景及工程的功能定位,并根据立交周边现状用地情况以及受制于立交范围内征地拆迁等因素,分近远期方案实施立交工程。通过分析研究,提出"定性分析功能定位是前提,定量分析节点交通量是依据,周边现状环境制约因素是最终立交方案能否实施的试金石"的设计思路,为城市主干路与城区段高速公路立交节点方案设计提供借鉴。
The determination of urban interchange node scheme is a selecting process of multilevel analysis,multi-objective decision and multifactorial constraint.The article introduces the engineering background and functional positioning.Based on the factors of present land situation surrounding the interchange and land acquisition subject to the interchange range,the interchange project is implemented on the short-term and long-term schemes.According to the analysis and study,the design thinking is put forward that the qualitative analysis of functional orientation is the premise,the quantitative analysis of node traffic volume is the basis,and the constraint factor of present surrounding environment is the touchstone whether or not to implement the interchange scheme finally,which provides the reference for the design of the interchange node scheme of the main trunk road in city and the expressway in city area section.
