【摘要】 根据对四川省彭州、简阳、德阳等灾区的砖石结构古塔震害的调查结果以及相关研究资料,通过分类与统计的方法,得到其不同破坏程度所占的比例,归纳出其典型震害特征,并对其成因进行了分析。分析结果表明:由于砖石结构古塔所采用的砌体材料本身的脆性性质以及粘结材料的强度不高,加之其自重大、重心高和顶部质量相对集中,使得其对地震扰动十分敏感,低烈度下发生开裂、高烈度下发生整体或局部垮塌的比例很大。分析结果可为砖石结构古塔的抗震性能研究提供借鉴。更多还原

【Abstract】 According to the seismic damage classification and statistics of Chinese ancient masonry buildings located in Pengzhou,Jianyang,Deyang,etc.in Sichuan province,as well as relevant research results,proportion of different damage degree and characteristics of typical seismic damage are summarized,while seismic damage origin is analyzed.Analysis results indicate that Chinese ancient masonry buildings are sensitive to the disturbance caused by earthquakes,while majority of them crack in low-intensity earthquake and collapse partly or integrally in high-intensity one,for the reason that the material and the bond are with low strength,structural weight is heavy,the centre of gravity is high,and the mass is concentrated in the top.It may provide theoretical base for seismic research on Chinese ancient masonry buildings.更多还原
