城市道路复杂交通节点改扩建设计思路探讨

Design Ideas Discussion on Reconstruction and Extension of Complex Traffic Nodes of Urban Road

在道路改扩建工程设计中经常遇到各种复杂的交通节点,笔者以万寿路南延工程为例,列举了工程中涉及的丰台站交通枢纽立交节点、四环快速路改造立交节点设计以及针对地铁影响区域的涉铁问题,并通过对复杂节点设计难点的分析,提出了科学合理的技术方案,为今后类似复杂交通节点设计提供有效的参考。

In the road reconstruction and extension project design often meets each kind of complex traffic node,the author take the Wanshou Road South Extension Project as an example,this paper lists the design of the interchange nodes of the traffic hub of the Fengtai District station,the interchange nodes of the transformation of the Fourth Ring Expressway,and the problems related to the railway in the areas affected by the subway,and analyzes the complicated nodes and technical difficulties,a scientific and reasonable technical scheme is put forward,which provides an effective reference for similar complex traffic node design in the future.
