摘要:: 依据5·12汶川地震中汶川县城(威远镇)11个区域共522栋房屋的房屋安全鉴定报告,深入统计分析房屋的震害情况及特点。结果表明,县城房屋倒塌较少,但破坏程度较重。破坏多集中在低层房屋以及砌体结构和木结构,而钢筋混凝土框架及高层房屋破坏较轻。结合房屋的破坏情况,对县城房屋的维修和加固情况进行分类统计,分析维修加固中出现的问题,并提出了相应建议。

Abstract:: On the basis of the appraisal reports of earthquake damage from 522 buildings in 11 districts of Wenchuan county(Weizhou town)after the 2008 Wenchuan Earthquake,earthquake damage and statistic in Wenchuan earthquake species was introduced.The damage features of multistory buildings of different kinds were summarized and analyzed.The results showed that the building collapse was less.However,the buildings were heavily damaged.The results indicated that the seismic capacity of RC frame buildings was stronger than those of brick buildings,timber structures and stone masonry structures.The damage to high-rise buildings was slighter than that to low-rise buildings.Based on the damage to buildings during Wenchuan earthquake,the different kinds of the damaged building reinforcement was made statistical analysis.The building reinforcement problems are need to be solved and some suggestions are given.
