摘　　要：针对我国村镇房屋抗震能力普遍较差的现状,为进一步掌握江西辖区,特别是位于地震重点监视防御区内的村镇房屋抗震能力现状,对江西省辖区内多个城市中的8个县(市)24个乡镇72个自然村开展村镇房屋抗震能力调查,其中详细调查了363栋江西典型村镇房屋。本文首先总结了江西的地震背景及村镇房屋震害特点;然后,依据调查资料,并结合九江地震等历史震害,指出江西村镇房屋在抗震设计、构造、施工中存在的不足。给出了江西村镇房屋不同结构类型、不同地区的震害预测结果,对比分析了不同结构类型及不同地区村镇房屋的抗震性能,总结了江西省既有村镇房屋的抗震能力现状;最后,针对江西村镇房屋,提出增强村镇房屋抗震性能的有效建议,本文研究可为村镇房屋的防震减灾工作提供参考。With regard to the present situation of rural buildings＇ poor seismic capacity generally in our country, and in order to further master the seismic capacity of rural buildings in the area of Jiangxi, especially in significant earthquake monitoring and prevention area, we investigated rural buildings＇ seismic capacity of 8 counties, 24 towns and 72 natural villages of several cities in Jiangxi province, and 363 typical rural buildings were examined in detail. Firstly, the seismic background and seismic damage characteristics of rural buildings in Jiangxi are summa- rized; Then, according to the survey data and Jiujiang Earthquake in history, this paper points out the problems of rural buildings in the seismic design and construction. The seismic damage prediction results in different regions and different structural types of rural buildings are presented, and different structural types and the seismic capacity of ru- ral buildings in different regions are analyzed, and the seismic capacity of existing buildings in Jiangxi province are summarized ; Finally, in view of rural buildings in Jiangxi, effective measures to enhance the seismic capacity of rural buildings are proposed, which provide references for seismic prevention and disaster reduction of rural buildings.
