摘要 2007年6月3日云南普洱发生6.4级地震,震源深度仅5km。地震对当地各类建筑物和构筑物造成不同程度的破坏。本文根据此次地震现场调研,介绍了地震烈度分布与震区破坏等级划分,归纳了土木、砖木、砖混、框架结构房屋等建筑结构的震害情况,同时对供排水、交通、电力、通讯系统及水利工程等基础设施的破坏状况加以概括,并对各类结构的破坏原因进行了分类分析。总结了此次地震的震害特点,提出了未来村镇防震减灾工作的若干建议。 A M6.4 earthquake occurred in Pu'er of Yunnan province on Jun. 3, 2007, the focal point of which was at a depth of only 5 kin. Due to the impact of the earthquake, most of local buildings and structures suffered damage to varying degrees. Based on the field investigation, the intensity distribution and destruction grade in disaster area were introduced, the seismic damage of construction were investigated, which usually contained earth-timber structure, brick-timber structure, brick-concrete structure and frame structure. Meanwhile, failure of critical infrastructure such as water supply and drainage system, transportation system, electric power system, communication system and hydraulic engineering were also summarized, and the possible causes of various damages to construction and infrastructure were analyzed in terms of different categories. Finally, the characteristics of the damage in this event were concluded, several suggestions for future earthquake prevention and disaster mitigation in village and town were made in this paper.
