摘要
位于新疆8度区的库尔勒站采用了隔震设计,这是全国铁路站房首次采用隔震技术.本文分析了站房采用隔震设计的可能性,确定隔震目标,选择隔震支座,通过ETABS软件建立隔震与非隔震模型进行反应谱和时程分析.计算结果表明,站房采用隔震技术可有效降低地震反应,减少水平剪力和结构变形,实现水平地震作用降低一度、抗震措施降低一度的目标.高铁站房采用隔震技术具有较多优势,值得推广.
Abstract
Korla station in Xinjiang Province,is located in the areas of seismic precautionary intensity 8,adopts the seismic isolation design,which is the first time that the seismic isolation technology is used in railway stations in China.In this paper,the possibility of using the isolation design to the railway station was analyzed,the aim of isolation is decided and isolation bearings were selected.The station models with or without isolation were established by software ETABS,and the response spectrum and time history analysis were finished.The results show that integrated the isolation technology can effectively reduce the seismic response,reduce the horizontal shear force and structure deformation,and achieve the requirements of the reduced horizontal seismic action and details of seismic design that shall be taken as one grade less than the local seismic precautionary intensity.The use of seismic isolation technology in high-speed railway station has many advantages and is worthy of promotion.
