近几年来,世界范围内发生多次强烈地震,不仅造成了重大的人员伤亡,而且损毁了城市的基础设施,特别对桥梁结构造成了严重的损毁破坏,导致了巨大的财产损失。与桥梁结构抗震相关问题的研究工作变得尤为迫切。本文对2007年至今国外典型地震中桥梁震害资料进行了收集和整理,首先统计了桥梁震害的主要形式。然后以日本新澙地震、秘鲁地震和智利地震3个地震实例作以典型震害的具体介绍。最后以震害为依据给出桥梁抗震设防的对策浅析。
In recent years, numerous earthquakes in the world have not only caused heavy casualties but also damaged the urban infrastructure, causing serious damage and damage to the bridge structure, resulting in huge property losses. Research on the problems related to seismic response of bridge structures has become even more urgent. This paper collects and sorts the data of bridge damage in typical earthquakes from 2007 to the present. First, the main forms of bridge damage are calculated. Then, a detailed description of typical earthquake damage is given by three earthquakes, namely, the Shinjuku Earthquake in Japan, the Peruvian Earthquake and the Chilean Earthquake. Finally, based on the earthquake damage countermeasures for seismic protection of bridges are given.
