| 摘 要： | 对某厂大尺度混凝土楼盖开裂情况进行检测，并通过对混凝土板贯穿性裂缝进行计算及成因分析，表明除了荷载引起裂缝外，混凝土收缩及温度应力也是产生裂缝的主要原因．提出了控制裂缝的设计措施．

| Abstract: | We check mainly the cracks of the concrete slab. The perfoliate crack of the concrete slab is calculated and analyzed in this paper. It indicates that shrinkage of concrete and temperature stress are the main cause which produce the cracks expect of the load. We propose some designing measures about controling the crack. |

| Keywords: | crack temperature stress shrinkage of concrete large area |
