| 英文摘要 | Stress relaxation is an important phenomenon of viscous behaviour of clay. Current studies only concern the stress relaxation during loading and lack of that under complex loading conditions. This paper focuses on constitutive modelling of stress relaxation of soft clay during complex loading conditions. For this, a newly developed anisotropic elastic viscoplastic model of soft clays is adopted as a basis. The model is extended taking into account the swelling deformation at constant stress or the increasing of stress at constant strain for over-consolidated state of clay, which is inverse to the conventional viscoplastic behaviour for normally or lightly over-consolidation state. The extended model is verified by simulating a series of newly conducted stress relaxation tests during an undrained loading-unloading-reloading shear test on soft clay. |
