摘要
2020年1月16日新疆库车5.6级地震造成库车市塔里木乡居民房屋不同程度破坏。依据地震现场1个乡18个调查点的实地调查结果,初步分析此次地震的烈度分布和房屋震害特征。结果表明:地震灾区最高烈度为Ⅵ度,受灾面积为813.6 km 2,涉及185户685人,无人员伤亡;建造年代较早的砖木结构抗震安居房,由于抗震设防烈度较低,部分房屋抗震构造措施不完善,破坏程度相对较重;少数砖混结构房屋因地基沉降及地震叠加破坏作用,造成门窗洞口处墙体出现裂缝;框架结构房屋受场地地震动放大影响出现填充墙开裂现象。
On January 16th,2020,Xinjiang Kuche M S5.6 earthquake caused different damage to the houses in Tarim Township,Kuche City.Based on the field survey results of 18 investigation sites in one township,this paper preliminarily analyzes the earthquake intensity distribution and earthquake damage characteristics.It shows that the highest intensity in stricken area isⅥ,and the affected area is 813.6 km 2,involving 185 families and 685 people,no casualties.Due to low seismic fortification intensity and imperfect seismic structural measures,some of the buildings with brick and wood structure built earlier have relatively heavy damage.A small number of brick and concrete buildings have cracks in the walls at the openings due to foundation settlement and seismic superimposed damage.Infilled walls of frame structure buildings are cracked due to the amplification of ground motion.
