摘　　要：通过对云南漾濞M_(S)6.4级地震影响区范围内房屋震害调查发现,区域内土木结构房屋破坏较其他结构严重,主要分为“穿斗式”和“墙抬梁式”两种类型,两者在地震中的破坏虽有相同,但也各有特点。文章从两种类型土木结构房屋破坏比较明显的主体架构、屋顶、墙体和地基部位进行震害特点分析,结合调查情况发现造成房屋受损严重的主要原因为房屋自身结构缺陷抗震性能差、地震频发加重房屋震害、地形条件造成不均匀沉降。Through the investigation of the earthquake damage of buildings in the affected area of Yunnan Yangbi M_(S)6.4earthquake,it is found that the damage of civil buildings in the area is more serious than other structures,which can be divided into two types:“bucket through”and“wall lifting beam”.Although the damage of the two types in the earthquake is the same,they also have their own characteristics.This paper analyzes the characteristics of earthquake damage from the main structure,roof,wall and foundation parts of two types of civil structures.Combined with the investigation,it is found that the main causes of serious damage are the poor seismic performance of the house’s own structural defects,frequent earthquakes,and uneven settlement caused by topographical conditions.
