摘 要：为了改善建筑空间与结构综合利用之间的矛盾，达到站房建筑与桥梁使用功能的一体化，“站桥合
一”的新颖站房结构体系被广泛应用于大型枢纽铁路客站，并已逐步成为目前主流的站房形式。然而，在长
期车辆荷载所致的疲劳作用下，站房承轨层结构会因外部环境激励而不可避免地产生损伤累积。同时，在结
构设计过程中通常不考虑损伤所致的结构动力响应分析，因而难以明确受损后结构动力响应的合规性。鉴于
此，本研究以车辆荷载激励下的承轨层结构为主要研究对象，通过动力响应数值分析法，对比分析了损伤变
化下的位移时程曲线，进而为承轨层的结构设计及其运维监测提供可靠依据。 关键词：站桥合一；动力响应；位移时程曲线；承轨层

Abstract: To ameliorate the relationship between the spatial modeling of buildings and the
comprehensive utilization of structures, and to achieve the integration of station building requirements
and bridge function, the novel station building structure system of “station and bridge integration” has
been widely used in large hub railway passenger stations, and has gradually become the mainstream
station building form. However, under the action of fatigue caused by long-term vehicle load, the rail
bearing layer structure of station building will inevitably produce damage accumulation due to the
excitation of external environment. At the same time, the structural dynamic response analysis caused
by damage is often not involved in the process of structural design, so it is difficult to determine the
compliance of the dynamic response of the damaged structure. Based on it, this paper takes the rail
bearing layer structure under the facilitation of vehicle loading as the main research object. Through
the dynamic response numerical analysis method, the displacement time history curve under the change
of damage is compared and analyzed, so as to provide a reliable basis for the structural design of rail
bearing layer and its operation and maintenance monitoring. Keywords:
