| 摘 要： | 根据四川荣县M_S4.7、M_S4.3、M_S4.9地震现场灾害调查资料,分析房屋震害特征和人员伤亡情况,结果表明震区房屋破坏类型主要为砖混结构、砖木结构和土木结构,其中砖木结构和土木结构受损比较严重,人员伤亡主要由房屋损坏导致;造成此现象的原因主要是该地区房屋建造年代久远,房屋结构不合理、抗震性能差,短时间地震频发造成震害累积,再加上民众防震减灾意识薄弱等。

| Abstract: | The seismic damage characteristics of buildings and associated human injuries were analyzed based on field investigation data obtained for the MS4.7, MS4.3, and MS4.9 earthquakes in Rong County, Sichuan Province. The results indicate that the types of building predominantly damaged in the disaster area are masonry-concrete structures, brick-wood structures, and civil structures; of these, brick-wood and civil structures are more vulnerable to seismic damage. Human injuries mainly occurred in relation to building damage. The main reasons for these phenomena are the old ages of buildings in the area, the inadequate building structure, and the poor seismic performance of the houses. In addition, frequent earthquakes occurring within a short time frame caused a remarkable accumulation of earthquake damage, and people in the area were knew little about earthquake prevention and mitigation. |
