Elasto-Plastic Constitutive Model Considering the Influences of Soil Structure and Anisotropy

Abstract:

Structure and anisotropy are two fundamental aspects of natural clays. They cant be ignored because of their significant influences on soils strength and stress-strain behavior, etc. Therefore, anisotropic tensor and structural parameters are introduced in Modified Cam Clay Model which is only suitable for isotropic remolded clays, and evolution laws of them are given in this paper. Thus, an elasto-plastic constitutive model considering the influences of natural soil structure and anisotropy is established. Most parameters involved in this model have explicit physical meaning and are easily determined through geotechnical tests, which makes this model more flexible, practical and applicable to practical engineering.
