【摘要】 自1992年4月23日云南孟连西中缅交界6.7、6.9级地震始,地震部门对云南地区的破坏性地震进行了现场灾害调查和经济损失评估。1992~2003年,云南地区共发生50次破坏性地震,积累了丰富的震害资料。本文根据云南地区的主要建筑结构,统计分析了50次地震不同烈度区的破坏比、损失比和震害指数,给出了房屋建筑的震害矩阵。更多还原

【Abstract】 Seismological departments have begun to make investigations on the earthquake damage and assess economic losses on the spot in the Yunnan area since the earthquakes with M_S6.7 and M_S6.9 that occurred on the boundary between China and Myanmar west of Menglian county, Yunnan Province, on Apr. 23, 1992. From 1992 to 2003, 50 destructive earthquakes had occurred in Yunnan. The data of seismic hazard had richly accumulated. Combining with the main house constructions, earthquake damage ratio, loss ratio and seismic hazard index in the areas with different earthquake intensity of the 50 events are systemically counted and analyzed, and seismic hazard matrix of house constructions in the Yunna area is given.更多还原
