摘　　要：接触网系统在抗震设计方面缺乏系统性的规范和标准,目前通常采用的接触网系统抗震设计方法由于在简化计算模型、输入反应谱或地震波方式、分析方法及计算结果等方面存在不确定性,无法准确预测接触网系统的破坏模式和薄弱位置。本文结合接触网系统在地震作用下的震害及抗震研究成果,从接触网系统、零部件、支柱、基础等方面对接触网系统提出系列抗震措施,以提升接触网系统的抗震性能;同时提出在补偿坠砣处增设耗能设施的减震措施,降低接触网系统的地震响应,有效提升电气化铁路防灾能力。The OCS lacks systematic specifications and standards in terms of seismic design.At present,the commonly adopted seismic design of OCS has some uncertainties in terms of simplified calculation model,input response spectrum or seismic wave method,analyzing method and calculation results,and it is unable to accurately predict the failure mode and weak position of OCS.With connection to the seismic hazards and seismic research results of OCS under earthquake,this paper puts forward a series of seismic measures for OCS from the aspects of OCS,fittings,masts and foundations so as to improve anti-seismic performance of OCS.At the same time,with connection of research results,the paper puts forward that the mitigation measures of energy dissipation facilities are provided for the tensioning weights so as to reduce the seismic response of OCS and effectively improve the disaster prevention performance of electrified railway.
