摘　　要：基于漾濞6.4级地震现场震害调查的结果,简要介绍了穿斗木构架民居的结构布置形式,对穿斗木结构的破坏现象进行分类和归纳,并得出穿斗木结构的整体破坏程度重于砌体结构与混凝土框架结构的结论。对比芦山7.0级地震中穿斗木结构震害较砌体结构和混凝土框架结构轻的现象,从地震动差异及围护墙差异两个方面给出了初步解释。结合现有的研究成果,对穿斗木结构的改进与加固提出了建议。This paper introduced the structural layout of the Chuandou-type timber frames folk houses,based on the results of earthquake damage investigation of Yangbi M6.4 earthquake,classified and summarized the failure phenomena of Chuandou-type timber frames,and drew the conclusion that the overall failure degree of Chuandou-type timber frames is higher than that of masonry structures and concrete frame structures.Compared with the phenomena that the damage of the Chuandou-type timber frames is slighter than that of the masonry structures and the concrete frame structures in the Lushan M7.0 earthquake,a preliminary explanation is given from the difference of the ground motion and the difference of the retaining wall.Based on the existing studies,some suggestions on the improvement and reinforcement of the Chuandou-type timber frames are put forward.
