【摘要】：从1993年1月27日的云南普洱6.3级地震到2015年3月1日的云南沧源5.5级地震,统计了云南省80次成灾地震,这些地震对云南造成了严重的灾害破坏和经济损失,很多农村地区是明显的受灾严重区,受灾面积较广泛。通过对这80次地震的房屋震害统计资料,统计了基于不同遭遇烈度下云南农村地区的各种类型房屋在五个破坏等级下的易损性矩阵,并求出不同结构在不同遭遇烈度的破坏比累积概率,绘制出其易损性曲线进行对比研究。参考这些云南农村地区的震害情况,为以后农村房屋抗震研究提供可靠地数据,总结云南农村地区现在抗震设防状况。
[Abstract]:From the Yunnan Pu'er earthquake (M = 6.3) on January 27, 1993 to the Yunnan Cangyuan earthquake (M = 5.5) on March 1, 2015, 80 disaster-stricken earthquakes were recorded in Yunnan Province. These earthquakes have caused serious disaster damage and economic losses to Yunnan. Many rural areas are clearly severely affected, with a wide range of affected areas. Based on the statistical data of the house damage caused by the 80 earthquakes, the vulnerability matrices of various types of houses in rural areas of Yunnan under different intensity are calculated under the five damage grades. At the same time, the cumulative probability of failure ratio of different structures in different intensity was calculated, and the vulnerability curve was drawn for comparative study. Referring to the earthquake damage in the rural areas of Yunnan Province, this paper provides reliable data for the future research on the earthquake resistance of rural houses, and sums up the present situation of earthquake resistance in rural areas of Yunnan Province.
