摘　　要：针对混凝土小型砌块建筑的墙体温度裂缝问题进行了探讨 ,调查了温度裂缝产生的部位及形式 ,分析了墙体温度裂缝的成因 ,总结了国内外防止温度裂缝的措施 ,并试图通过更为有效的有限元方法来解决温度裂缝问题。The concrete hollow pint sized block building is a new style structural system in China. But some difficulties, such as wall heat preservation, wall cracks and secondary fitment, disturb the application of this structural system. We discuss temperature cracks on the wall, investigate the position and types of temperature cracks in the concrete hollow pint sized block building, analyze the cause of temperature cracks, summarize the methods which prevent temperature cracks in the world. Finally we try to solve the question about temperature cracks through the more effective methods.

关 键 词：混凝土 空心砌块建筑 温度裂缝 温度应力 有限元
