摘　　要：对芦山7.0级地震芦阳镇307栋建筑物的现场调查资料进行统计分析,对各类建筑结构的工程震害特点进行总结,并对其破坏原因进行简析,取得以下成果:以芦阳镇为例,研究了我国西南地区典型小城镇建筑结构类型的组成与分布特点;总结了砖混结构、砖混凝土结构、砖木结构、钢筋混凝土框架结构和高层结构的破坏特征;给出芦阳镇各类建筑结构的破坏比;并针对芦阳镇建筑结构分布和震害特点提出灾后重建建议,对芦阳镇恢复重建和今后我国小城镇防灾规划有重要的参考价值和指导意义。Damages of 307 building structures in Luyang was analyzed by using a statistical method. The town during Lushan earthquake, which has a magnitude of 7.0, damage characteristics and damage reasons were summarized for the various types of building structures. The conclusions obtained in this study are as follows： Taking Luyang town as an example, the building structure types and distribution are investigated for the typical small-towns in Southwest China. Damage characteristics are summarized for the five kinds of structures, i. e. masonry-concrete structure, masonry- reinforced concrete frame structure, masonry-timber structure, reinforced concrete frame structure, and high-rise structure. The damage percentages are obtained for the various types of building structures in Luyang town. According to the building structure types, distribution, and are given, providing important references and planning. damage characteristics, suggestions for the post-earthquake reconstruction guidelines for the post-earthquake reconstruction and disaster prevention
