以上海浦东中环线东段金桥立交作为工程背景,介绍了城市现状枢纽互通立交改建工程的几种方案。探讨了一般现状立交改建的3种模式:全利用现状立交改建模式、部分利用现状立交改建模式、完全废弃现状立交改建模式。结合金桥立交改建的实际案例,分析选择了切实可行的改建方案。通过废弃现状金桥立交,采取完全新建方案后,改建后的金桥立交既满足了新的节点功能定位,也适应了城市的发展,其运行效果良好。
Taking the Jinqiao Interchange in the east section of Shanghai Pudong Central Loop as an example, several schemes for reconstructing the project of hub interchange in urban status quo are introduced. This paper discusses three modes of reconstructing the status quo interchange: making full use of the status quo interchange mode, partially using the status quo interchange mode, completely abandoning the status quo interchange mode. Combined with the actual case of Jinqiao interchange reconstruction, the analysis selected and implemented the feasible reconstruction plan. After abandoning the current status of Jinqiao Interchange and adopting a completely new plan, the reconstructed Jinqiao Interchange not only fulfilled the function of the new node but also adapted to the development of the city, and its operation effect was good.
