摘　　要：当地时间2023年2月6日4时17分土耳其南部与叙利亚接壤地区发生7.8级地震,之后下午1时24分又发生了7.5级地震,并有多次余震发生,造成了大量交通基础设施损坏。文中首先利用全方位反应谱分析了强度较大的地震动记录的特点,并探讨了其与断层的联系;然后,分别介绍此次地震中铁路、公路、航空和港口系统震害特点,并从统计角度分析铁路和公路在不同烈度区的震害状况,发现近断层和跨断层交通结构震害较严重;最后,讨论此次地震对我国交通结构抗震的经验与启示。A M s7.8 earthquake hit southern Turkey near the border with Syria at 4∶17 a.m.local time on February 6,followed by a M s7.5 earthquake at 1∶24 p.m.and numerous aftershocks,causing extensive damage to transportation infrastructure.In this paper,the characteristics of ground motion records with high intensity are analyzed by using omni-directional response spectrum,and the relationship between them and faults is discussed.Then,the earthquake damage characteristics of railway,highway,aviation and port systems in this earthquake are introduced respectively,and the relationship between the earthquake damage conditions and structural forms of railway and highway in different intensity areas is analyzed statistically.It is found that the earthquake damage of traffic structure near and across faults is more serious.Finally,the author discusses the experience and revelation of earthquake resistance to Chinese traffic structure.
