摘　　要：以农村地区常见的夯土墙房屋为研究对象,分析了纵横墙交接处裂缝的成因,并采用数值分析方法对其进行自重和地震作用下的计算,得到了纵横墙交接处墙体的受力和变形特点,进而阐明了纵横墙交接处裂缝的产生和开展机理;提出了设置木圈梁这一裂缝控制措施,通过设置木圈梁前后的受力分析对比,验证了其有效性.With rammed earth houses for the study, the causes of the wall cracks of vertical and horizon- tal junction were analyzed. With finite element analysis method, its weight and seismic calculations were made, the force and deformation characteristics of the wall of vertical and horizontal junction were got, to further clarify the mechanism of the wall cracks of vertical and horizontal junction. After the control meas- ure of wood ring beam was set, its validity was verified by comparing the analysis results with the results without wood ring beam.
