2008年5月12日，中国西南部四川省发生毁灭性地震，造成69227人死亡，374,643人受伤，地震发生5个月后，仍有17,923人下落不明。这次地震的震中位于汶川县，引发的断层破裂长度约300公里，穿过北川县向东北延伸，到达青川县；断层两侧的许多城镇遭到严重破坏/摧毁，达到XI级地震破坏强度。本文通过对汶川县映秀镇、北川县北川镇和什坊市汉旺镇三个受灾最严重的城镇的破坏情况的描述，介绍了地震工程现场调查队(英国结构工程师学会)和欧洲委员会联合研究中心欧洲结构评估实验室进行的震后实地勘察任务的结果。这项工作的重点是描述灾难中和灾后的建筑性能，特别是钢筋混凝土框架、钢筋混凝土约束砖石、无筋和无约束砖石、工业、当地乡土和历史建筑。本文提供的信息和建议对今后类似地震危险区的工程应用具有一定的参考价值。
A devastating earthquake struck the southwestern Chinese province of Sichuan on 12 May 2008, leaving 69,227 dead and 374,643 injured, with 17,923 people still missing five months after the main event. The epicentre of the earthquake was located in Wenchuan County, which triggered a fault rupture length of about 300 km, stretching northeast through Beichuan County and reaching Qingchuan County; many towns on both sides of the fault were severely damaged/destroyed, reaching an earthquake damage intensity of XI. This paper presents the findings of a post-earthquake reconnaissance field mission carried out by the Earthquake Engineering Field Investigation Team (The Institution of Structural Engineers, UK) and by the European Laboratory for Structural Assessment of the Joint Research Centre of the European Commission, through the description of the damage sustained by three of the towns that suffered the largest levels of devastation: Yingxiu Town of Wenchuan County, Beichuan Town of Beichuan County, and Hanwang Town of Shifang City. The work focuses on the description of building performance during and after the disaster, in particular of reinforced concrete frame, reinforced concrete confined masonry, unreinforced and unconfined masonry, industrial, local vernacular and historical buildings. The information and recommendations provided in this paper will be useful for future engineering applications in similar earthquake risk regions.
