摘　　要：根据芦山地震极震区和重灾区古建筑的震害现场调查资料,进行震害特征与破坏原因分析。古建筑结构形式主要包括木结构、石结构、砖木结构和砖石结构。通过分类和归纳的方法,得到古建筑的典型震害特征包括基础剪断、墙体开裂、抹灰掉落和顶部局部塌落等。古建筑遭到破坏的成因机制包括:鞭鞘效应、竖向地震作用、传力机理变化等。分析了不同结构形式古建筑的地震破坏作用差异性等,同种结构形式的古建筑比普通房屋建筑的抗震性能要好。同时,讨论了不同结构类型古建筑的抗震维护与加固措施、抗震传力机理以及隔震和减震等,为古建筑抗震设防和抗震加固、减轻灾害等提供参考。Based on the data of field investigation, researches on characteristics and causes of ancient buliding damage in meizoseismal region and severely damaged structure form mainly includes wood structure, stone Through region induced by Lushan earthquake are carried out. The structure, brick wood structure and brick stone structure. the methods of classification and induction, it is found that the typical damage characteristics mainly in- clude shear cut of base, walls fracture, plastering drop, and local collapse of the top. The formation mechanism of the destroyed ancient buildings are the vertical seismic action, whipping effect, change of force transferring mecha- nism. The damage differences induced by Lushan earthquake of different structures of ancient buildings are ana- lyzed. The anti-seismic capacity of ancient buildings is better than ordinary buildings under the same structure. Meanwhile, the reinforcement and maintenance methods of seismic fortification, anti-seismic force transferring mechanism, and the techniques of seismic isolation and shock absorption concerning different ancient buildings are discussed. Therefore, the obtained results can offer reference to earthquake fortification of ancient buildings, and the reduction of damage loss.
