| 摘 要： | 将损伤理论引入到粘土地基沉降计算中，修正已有沉降计算公式。根据Duncen-Chang模型考虑了泊松比ν随应力变化而对地基沉降产生的影响。认为次固结沉降是土骨架蠕动变形的结果,用Mesri蠕变模型计算土的次固结沉降。

| Abstract: | In this paper, damage mechanics was used in calculation of clay foundation settlement and former foundation settlement formula was amended. On the basis of Duncen-Chang model, effect of varying with stress on settlement was considered. In view of sub-consolidation settlement is caused by soil creep deformation, Mesri creep model was used to calculate sub-consolidation settlement. |
