ELASTIC-PLASTIC DAMAGE MODEL OF CEMENT-STABILIZED SOIL

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.
