摘要
对混凝土收缩、徐变和施工等因素产生变形裂缝的机理进行了研究,对混凝土收缩、徐变的计算公式作了分析,并指出大体积混凝土温度裂缝的产生主要受收缩、徐变、水泥水化热以及外界气温变化的影响。
It makes a research on the mechanism of deformation crack caused by concrete shrinkage, slow change and constrution, analyses the formula to calculate concrete shrinkage and slow change, and points out that large bulk concrete temperature crack are mainly caused by shrinkage, slow change, cement hydration heat and temperature change outside.
