摘　　要：2019年12月26日湖北省应城市发生4.9级地震,地震对震中区域附近村镇建筑物造成了不同程度的破坏。通过对6个乡镇近百个村落的建筑物震害情况调查分析,总结了实心墙砌体结构、空斗墙砌体结构、砖木结构、土木结构和非结构构件的震害特点,并从结构布置、施工材料和工艺、抗震构造措施三个方面分析了建筑物破坏原因。总结本次地震的震害特点,可丰富湖北省村镇房屋的震害资料,为长江中游村镇房屋震害预测提供基础依据,为后期政府落实防震减灾措施指明方向,具有重要的社会意义。A 4.9 magnitude earthquake occurred in Yingcheng City,Hubei Province on December 26,2019.This earthquake damaged the buildings in the epicenter area to different degrees.Based on the investigation and analysis of the building seismic damage in 6 towns(nearly 100 villages),this paper summarizes the seismic damage features of solid-wall masonry structure,rowlock-wall masonry structure,brick-wood structure,raw soil-wood structure and non-structural components.The causes of building seismic damage are analyzed from three aspects:structural layout,construction materials and technology,and seismic construction measures.It is of social significance to investigate and summarize the building seismic damage,which can enrich the seismic damage data of rural buildings in Hubei,provide a basis for earthquake damage prediction,and show a way for the government to implement measures for earthquake prevention and mitigation.
