摘要: 水泥加固土作为一种弹塑性介质,但很难用通常的弹塑性模型来描述。本文通过对水泥加固土的损伤试验得到的一系列损伤关系曲线的分析,分别推导建立了水泥加固土的弹性与损伤、塑性与损伤本构关系并首次建立了水泥加固土的弹塑性损伤模型。通过与损伤试验结果的对比,证明了本文所建立的水泥加固土的弹塑性损伤模型是合理的。

Abstract: As a kind of elastic-plastic medium, it is very difficult to describe Cement-stabilized soil by usual elastic-plastic models. A series of damage relationship curves obtained from the damage experiments of cement-stabilized soil are analyzed. The constitutive relationships of elastic damage and plastic damage are established, respectively. The elastic-plastic damage model of cement-stabilized soil is first established. Through the comparison with the experimental results, the elastic-plastic damage model of cement-stabilized soil is verified.
