深圳地铁3号线高架车站结构设计研究

研究目的:随着城市轨道交通建设的快速发展,高架线路的增长比例更快.如何在高架车站的结构选型和设计方面取得优势,将高架车站对城市空间的影响降到最低成为亟待解决的问题.本文结合深圳地铁3号线工程和其他城市地铁建设经验,对高架车站常用结构方案及设计要点进行分析和研究,为类似高架车站设计提供参考.研究结论:根据深圳地铁3号线“建桥一体化”高架车站结构受力特性,采取针对性的结构设计措施和验算手段,可以对该类结构特点扬长避短,满足轨道交通对高架车站结构安全性和乘客舒适性要求.

Research on Structure Design of Elevated Station of Line 3 of Shenzhen Metro

Research purposes: With the rapid development and construction of urban rail transit,the percentage of the elevated track grows faster.How to gain an advantage in model selection and design of the elevated station structure and how to cut the impact of the elevated station on the city space as much as possible become the problems to be solved urgently.With combination of the construction experience of Line 3 of Shenzhen metro and metros of other cities,this paper analyzes and researches the commonly used structure scheme for the elevated station and the key points of design to provide some useful references to the similar elevated station. Research conclusions:According to the load-bearing characteristics of the elevated station structure with "integration of building bridge structure" of Line 3 of the Shenzhen metro,the targeted measures for the structure design were taken and the relative checking methods were used.In this way,the good points and shortcomings of the such kind structure could be adopted and avoided to meet the requirements of the structure safety of the elevated station and passengers′ comfortableness of urban rail transit.
