龙东大道快速化涉及规划轨道交通方案深化研究

Further Research on Scheme of Longdong Avenue Expressway and Planned Rail Transit

在道路改扩建工程设计中经常遇到各种复杂的交通节点,以龙东大道快速化工程为例,列举了工程中涉及的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,结合轨道交通线路规划控制的常规技术参数及高架桥梁结构桩基对地铁规划线位的影响等多角度,针对复杂的交通节点多轮次优化协商设计方案,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 design of road reconstruction and extension projects,various complex traffic nodes are often encountered.Taking the expressway project of Longdong Avenue as an example,the issues related to the affected areas of the subway in the project are listed.Through the analysis of the design difficulties of complex nodes,combined with the conventional technical parameters of rail transit line planning and control,and the impact of elevated bridge structure pile foundation on the subway planning line position,and aiming at the complex traffic nodes,the multi-round optimization and negotiation are carried out for the design scheme.Finally,a scientific and reasonable technical solution is proposed,which provides the effective reference for the design of similar complex traffic node in the future.
