［摘要］從1993年1月27日的云南普洱6.3級地震到2015年3月1日的云南滄源5.5級地震，統(tǒng)計(jì)了云南省80次成災(zāi)地震，這些地震對云南造成了嚴(yán)重的災(zāi)害破壞和經(jīng)濟(jì)損失，很多農(nóng)村地區(qū)是明顯的受災(zāi)嚴(yán)重區(qū)，受災(zāi)面積較廣泛。通過對這80次地震的房屋震害統(tǒng)計(jì)資料，統(tǒng)計(jì)了基于不同遭遇烈度下云南農(nóng)村地區(qū)的各種類型房屋在五個(gè)破壞等級下的易損性矩陣，并求出不同結(jié)構(gòu)在不同遭遇烈度的破壞比累積概率，繪制出其易損性曲線進(jìn)行對比研究。參考這些云南農(nóng)村地區(qū)的震害情況，為以后農(nóng)村房屋抗震研究提供可靠地?cái)?shù)據(jù)，總結(jié)云南農(nóng)村地區(qū)現(xiàn)在抗震設(shè)防狀況。

Abstract: There are 80 damaged earthquake counted from the 6.3 magnitude earthquake of Puer on January 27, 1993 to 5.5 magnitude earthquake of Cangyuan on March 1, 2015. These earthquakes cause serious damages and economic losses on Yunnan. Many rural areas are significantly serious disaster-stricken with extensive disaster-stricken areas. Based on housing seismic damage statistics about the 80 earthquakes, the vulnerability matrix of various types of housings in rural areas in Yunnan province under five damage grades under the different seismic intensities was counted. The cumulative probability of damage ratio of different structures under different seismic intensities was calculated, and relevant vulnerability curves were drawn to compare and study. Based on the seismic damage situations in these rural areas of Yunnan, reliable data can be provided for the future seismic study of rural housings and can be used to sum up the current seismic precautionary situation in rural areas of Yunnan.
Keywords: Yunnan rural building； structure type； damage ratio； vulnerability curve； vulnerability analysis
