摘　　要：红粘土是亚热带气候条件下形成的一种特殊土质,含有红粘土的地基土多具有上硬下软的特点,为天然地基软弱下卧层。应用损伤力学研究红粘土地区水泥土的损伤机制,通过试验得到有关参数,并且推导了红粘土的损伤演化及本构方程。Groundwork bearing red clay,which is a special soil formed in semitropical climate,is often hard in upside and soft in underside, which makes the groudwork natural soft substratum. Studying the damage mechanism of cemented soil in red clay area based on damage mechanics, it has obtained some relating parameter through experiment, and deduced the damage evolvement of red clay as well as the constitutive equation.
