摘　　要：基于云南省1993年至2015年发生的80次地震震害数据资料,分别统计出了云南省城市和农村不同烈度区在五个破坏等级下的易损性矩阵,求出相同地震烈度下不同烈度区房屋建筑破坏比累计概率平均值。当地震烈度相同时,云南省城市高烈度区房屋建筑破坏比累计概率平均值比低烈度区小,虽然云南省农村地区多为自建房屋,大部分没有按照抗震设防标准来设计施工,但是农村地区房屋建筑破坏比累计概率平均值也呈现相似的规律性。这为云南省城市和农村地区房屋建筑加固、改造和灾后损失评估提供依据。Based on the data of 80 earthquakes in Yunnan Province from 1993 to 2015,the vulnerability matrices of enforcing zones in urban and rural areas in Yunnan Province under five damage levels were calculated,the average value of cumulative probability of failure under the same intensity in different regions of Yunnan Province is obtained.In urban areas,the cumulative damage probability in high fortification intensity areas is lower than that in low fortification intensity areas under same seismic intensity,which is also applicable to rural areas,although it is well known that buildings in rural areas are almost self-built,of which the construction is not according to seismic fortification criterion.It provides the basis for the improvement and assessment of post-disaster loss of buildings in urban and rural areas in Yunnan Province.
