| description | The invention discloses a method for constructing a loess damage statistical constitutive model. The method specifically comprises the following steps: step 1, collecting an on-site loess soil sample and obtaining physical parameters and mechanical parameters of the loess soil sample; 2, the deformation modulus and the apparent stress of loess are obtained based on the physical parameters and the mechanical parameters obtained in the step 1; 3, based on the deformation modulus and the apparent stress of the loess, obtaining a deviatoric stress model borne by the loess infinitesimal element; and 4, constructing a loess damage statistical constitutive model through the model of the deviatoric stress borne by the loess infinitesimal elements. According to the method, the influence of the water content and the confining pressure is introduced into the loess deformation modulus, the constructed loess constitutive model data is fit with the actual environment condition, the construction safety and the influence on |
