铁路建桥合一站房结构概念设计问题探讨

城市人口激增带来了铁路交通巨大客流,建桥合一站房作为新兴的铁路旅客站房形式应运而生。其中一种类型的建桥合一站房将铁路桥梁承轨层融入房屋结构中,引起了房屋结构设计上的诸多须关注的问题。本文结合红岛站、济南东站、雄安站、昆明南站等工程实例,对该类站房结构设计进行总结分析,阐述了该类结构选型、单元划分、荷载取值、抗震设计等方面的概念设计思路和方法,从而实现小震不坏、中震可修、大震不倒的抗震设计目标,保证站房的结构安全。

Discussion on Conceptual Design of Integrated Railway Station Structure Consisting of Bridge and Building

As the rapid increase of urban population has brought about a huge passenger flow of railway traffic the new construction of integrated station structure consisting of bridge and building has emerged.One type of integrated station structure consisting of bridge and building integrates the rail bearing layer of the railway bridge into the building structure which brings a lot of problems that need to be concerned about the building structure design.This paper summarized and analyzed the structur design of Hongdao Station Jinan East Station Xiongan Station Kunming South Station and expounded the conceptual design ideas and methods in terms of type selection unit division load value and seismic design of this type of structure so as to realize the anti seismic design objective of no damage under small seismic repairable under medium seismic and no collapse under large seismic and ensure the structure safety.
