摘要:
吉林省松原市地震频发,震后震害明显,损失较大。但由于发生的地震震级较低,且震中位置不在大中城市而未受到广泛重视,因此非常有必要对该地区群体建筑的抗震能力和地震风险进行分析。文中以松原市查干花镇和宁江区的群体建筑结构为研究对象,利用城市震害模拟器YouSimulator,输入2017年7月23日松原4.9级地震的实测地震动与20条历史地震动进行地震响应分析,对城市和乡镇的结构损伤情况进行了对比,并进一步分析了两地群体建筑结构的地震风险。分析表明:不考虑经济损失时,乡镇的地震风险高于城市。考虑经济损失后,城市的地震风险高于乡镇。文中的研究成果可以为松原地区的震前防灾减灾,以及震时应急救灾,震后恢复重建提供参考依据。
Abstract:
There were frequent earthquakes in Songyuan City,Jilin Province,which resulted in the obvious structural damage and large economic loss. Because the earthquake intensities were weak and the epicenter locations were not in the large and medium-sized cities,which have not caught the extensive attention. So the seismic performance and earthquake risk of the building groups in this area should be researched. The group structures of Chaganhua Town and Ningjiang District of Songyuan City were modeled in the urban earthquake damage simulator (YouSimulator),and the seismic responses analysis was conducted with the measured ground motions of the Songyuan M4.9 earthquake on July 23,2017 and 20 historical ground motions. The structural damage of city and town were compared,and the earthquake risk of group structures was evaluated. The analysis shows that when the economic losses are not taken into account,the earthquake risk of town is higher than that of city. After considering the economic losses,the earthquake risk of city is higher than that of town. The research results of this paper can provide important basis for the disaster prevention and reduction policies before earthquakes,emergency rescue during earthquakes,and post-earthquake recovery and reconstruction in the Songyuan area.
