摘　　要：假设损伤变量D服从二参数的Weibull分布,建立一种新的损伤模型,推导出本构方程,并将其运用到硫酸盐侵蚀后砂浆的性能研究。大量的试验证实了假设的合理性。A new damaging model is established if damaging parameter D is supposed to obey Weibull distributing, and the cured equation of relationship between stress and strain can be deduced from this model, then using it we can well studied mechanical properties of mortar corroded by sulfate.Experiments prove that the hypothesis is reasonable.

关 键 词：损伤变量D WEIBULL分布 砂浆 硫酸盐侵蚀 本构方程
