混凝土界面开裂模型

INTERFACE CRACKING MODEL FOR CONCRETE

  • 摘要: 本文利用Eshelby等效原理1.给出了混凝土骨料与砂浆之间由于温度升高或湿度损失而造成界面破坏的条件。并根据水化热传导和水份扩散造成的非均匀温度和湿度场性质,讨论了混凝土材料热源裂缝与干缩裂缝的分布特征。

     

    Abstract: Based on Eshelby's equivalence theory,the conditions of the interface cracking between aggregate and mortar due to the loss of moisture and the fall of temperature are given. The distribution characteristics of the thermal cracks caused in hydration and the dry cracks caused in the water diffusion of concrete are discussed.
