| 摘 要： | 通过对某高层建筑转换大梁的两侧垂直裂缝进行了全面分析和计算，证明裂缝是由温度骤降产生自约束应力引起的，并进行模板的保温保湿分析；提出预防厚壁梁开裂对策，为类似混凝土厚壁梁施工和设计提供了指导性的建议。

| Abstract: | Through the analysis of two vertical cracks in transition-girder of high-rise building, it is proved that the cracks are caused by restricted stress due to sudden temperature variation. In this part, warm-keeping and moisture-keeping by form are analyzed. Some counter-measures to prevent thick-wall beam from cracking are given. Some instructive suggestions for design and construction of concrete thick-wall beam are provided. |

| Keywords: | crack of concrete the temperature stress shrinkage of concrete thick-wall beam |
