摘　　要：为探明高层住宅填充墙裂缝产生的原因,阻止裂缝进一步发展,结合太原市某小区高层住宅房屋,开展裂缝的现场实际分布调查研究,并通过统计学的方法,得出结果:墙体损伤为非承重结构构件(填充墙)损伤,裂缝主要为加气混凝土砌块(填充墙)与混凝土剪力墙(承重墙)之间的竖向裂缝、墙体线管位置裂缝、窗角下裂缝和隔墙(非承重构件)裂缝。这些裂缝对主体结构安全性不造成影响,但局部墙体漏雨以及玻璃崩裂,影响观感,且会对使用功能产生影响。建议对产生裂缝的墙体进行封闭处理,避免漏雨对墙体的侵蚀,进而提出裂缝的预防措施,以此提高工程墙体结构的质量。With a high-rise building in Taiyuan as an example,an investigation of the actual distribution of cracks was conducted by statistical means to explore the causes of cracks on filling walls of a high-rise building and to prevent worsening of cracks.The results showed that wall damage appeared in a non-load-bearing structural member(filled wall)and that crack type mainly included vertical cracks between aerated concrete block(filling wall)and concrete shear wall(bearing wall),cracks on a wall pipe,as well as cracks under the window corner and the partition wall(non-load-bearing members).These cracks did not affect the safety of the main structure,but they might cause local wall leakage,glass cracking,physical appearance and most importantly,decreased serviceability.Therefore,the paper proposes that wall cracks should be closed to avoid the erosion of rain leakage to the wall and give preventive suggestions to improve the quality of wall structure.
