城市立交桥与地铁重叠段地梁设计

摘要:

随着城市化不断建设与发展,难免出现城市桥梁与地铁线位相冲突的情况。广州市某快速化改造工程部分立交桥与城市已运营地铁线重叠,由于受地铁结构影响所限,需合理设置地梁避让地铁结构以保证桥梁线位通顺。该文结合项目特点主要介绍工程节点地梁的设计与计算方法,并通过midas建模分析提出在其过程中的注意事项,以供其他类似情况的工程参考。

Abstract:

With the continuous construction and development of urbanization, it is inevitable that there will be phase conflicts between urban bridges and subway lines. Part of the overpass of a rapid transformation project in Guangzhou overlaps with the railway line of the urban transported camp. Due to the influence of the subway structure, it is necessary to reasonably set the ground beam to avoid the subway structure to ensure the smoothness of the bridge line. Combined with the characteristics of the project, this paper mainly introduces the design and calculation method of Engineering node ground beam, and puts forward the matters needing attention in the process through Midas modeling analysis, so as to provide reference for other similar projects.
