摘　　要：空斗墙是早期砖石结构中较传统的结构形式,在老旧房屋检测中常有遇到,但由于其整体性和抗震性均较差,现行规范中已明确取消了该类结构,故现行相关规范中均无法找出空斗墙的检测评定依据,计算软件中也无空斗墙结构体系。本文通过长期的工程实践经验总结了空斗墙结构的现场检测要点,并通过对历代砌体设计规范的研读,提出了对空斗墙结构采用普通黏土实心砖墙模拟,通过修改材料容重、修正墙体受压承载力,得出符合空斗墙实际情况的计算结果;最后介绍了空斗墙结构的抗震性评定方法,为空斗墙结构的老旧房屋现场检测与安全性评定提供参考。Cavity wall is a traditional structure form in early masonry structure,which is often encountered in the inspection of old buildings.However,due to its poor integrity and seismic capacity,this kind of structure has been explicitly canceled in the current norms,so the detection and evaluation basis of cavity wall cannot be found in the current relevant norms,and there is no structural system of cavity wall structure in the calculation software.Through long-term engineering practice experience,this paper summarizes the main points of field inspection of cavity wall structure,and through the study of masonry design norms in the past,it proposes to use common clay solid brick wall simulation of cavity wall structure,through modifying the material bulk density and modifying the wall compression capacity,it obtains the calculation results in line with the actual situation of cavity wall structure.Finally,the seismic resistance evaluation method of cavity wall structure is introduced.It provides reference for the field inspection and safety assessment of the old buildings with cavity wall structure.
