丰台站结构体系研究与设计

Research and Design of Fengtai Railway Station Structure

丰台火车站为我国首次采用双层车场的建桥合一结构形式的特大型综合交通枢纽,涉及公交、地铁、普速国铁、高速高铁、商业等多种建筑功能,结构形式及荷载状态十分复杂。本文对其结构设计采用的设计标准、主要结构方案进行了简要介绍,并对基础设计、结构分缝原则及滑移缝设置、结构超限分析及抗震性能目标的确定、列车振动舒适性分析、钢结构屋盖稳定性等几个重难点问题进行了提纲挈领式的论述,相关分析内容、设计方法可为其他类似工程提供借鉴。

Fengtai Railway Station is the first large-scale comprehensive transportation hub in China to adopt the structure of double-deck yard,which combines building and bridge.This paper briefly introduces the design criteria and main structural schemes adopted in its structural design,and also introduces the basic design,the principle of structural slip and the setting of slip joints,the structural over-limit analysis and the seismic performance objectives.Several key and difficult problems,such as determination,analysis of train vibration comfort and analysis of overall stability of the steel roof,are discussed.It provides reference for other similar projects.
