摘　　要：2007年6月3日云南宁洱发生6.4级地震。对宁洱县城区的砖混结构、框架结构、底层框架结构及空旷房屋等共15幢建筑的典型震害进行了分析。结果表明,造成建筑物破坏较重的主要原因有:①地基不均匀沉陷;②设计不合理;③设防烈度低;④施工质量差,砂浆标号低;⑤沉降缝不规范;⑥震害累积效应;⑦孤立山包及边坡陡坎影响等诸多因素。The typical disasters of fifteen buildings （including multi-storey brick buildings, RC frame buildings, bottom frame buildings and spacious buildings） in the Ning ＇er county town caused by the Ning ＇er Ms6.4 earthquake have been analyzed. The results indicate that the serious damage is mainly due to following factors： asymmetrically settlement of groundsill, irrational design, low antiseismic intensity, bad construction quality, low Mortar grade, nonstandard settlement joint, cumulation of earthquake disasters, isolated hill and scarp slope effects.
