铁路站房抗震设防策略探讨

Investigate about Railway Station Seismatic Fortifies Strategies

国内铁路站房的体型、规模、功能各不相同,本文结合国内部分铁路站房的现状调查、抗震设计与审查工作,提出了合理确定铁路站房的抗震性能目标、抗震防线、结构体系与关键构件、重要节点及其附属结构构件的抗震措施,是新建铁路站房抗震设防策略的关键。既有车站站房改造工程的抗震设防关键是通过对既有结构进行抗震鉴定、加固设计与安全评估,改善其抗震性能,满足正常使用需求。

Domestic railway station in size, scale, and functional each are not identical. Combined with the railway station of the present situation ofnd the seismic survey design and examination work, the reasonable seismic performance goals of railway station building, seismic line, structure system and key components, important node and the anti-seismic measures of its subsidiary structure component are put forward. These are the key to the seismic fortification strategy of newly built railway station. The aseismatie fortify key of station house renovation is to improve the aseismic performance and satisfy the demand of normal use through both the anti- seismic structure identification, the reinforcement design and safety assessment.
