武汉平安铺大型互通立交改造方案研究

Research on Reconstruction Scheme of Pinganpu Large-scale Interchange in Wuhan

摘要:

大型互通立交作为路网系统中的关键节点发挥着重要作用，而对既有大型互通立交的改造一直是城市开发建设中的难题。以武汉市平安铺大型互通立交为例，从现状问题和发展需求入手，对现状立交的改造策略进行宏观分析，并在总体方案比选、交通微观仿真、桥下空间利用等方面展开详细研究，将集约用地、提质增效理念植入改造方案。最终，阐明了大型互通立交改造在功能优化、运行稳定、用地复合等方面可采取的措施、方法。研究结论可为城市管理、建设运维、规划设计等相关人员提供借鉴。

Abstract:

Large-scale interchanges play an important role as key nodes in the road network system, and the reconstruction of existing large-scale interchanges has always been a challenge in urban development and construction. Taking the Pinganpu Large-scale Interchange in Wuhan as an example, starting from the current problems and development needs, a macro analysis on the reconstruction strategy of the current interchange is conducted, and the research on overall scheme comparison, traffic micro simulation, and utilization of space under the bridge are carried out in detail. The concept of intensive land use and improving quality and efficiency is integrated into the reconstruction scheme. Finally, the measures and methods that can be taken for functional optimization, operation stability and land use integration in the reconstruction of large-scale interchanges are elucidated. The research conclusion can provide guidance and reference for personnel related to urban management, construction, operation, maintenance, planning and design.
