Simulation on Strain Softening of over-Consolidated Clayey Soil by Binary Medium Model
This paper attempts to simulate the stress-strain relations of Pontida silty clay under triaxial tests in accordance with the latest theory of geotechnical nonlinear deformation analysis-breakage mechanics of geomaterials. The result proves that the binary medium model of over-consolidated clayey soil can effectively reflect the deformation mechanism of soil mass and the brittle break phenomenon, thus possessing good suitability and effectiveness. This also lays down the foundation and provides new ways for the further discussion of establishing the elastic-plastic constitutive model of clayey soil softening properties and intensity attenuation effects with the consideration of large shear displacement.
