Abstract

Extensive laboratory tests and field observations show that soft clay exhibits long-term deformation. For further understanding of the creep characteristics of soft clay, the mechanism of creep is first discussed from the microscopic physicochemical viewpoint. Then, the evolution of second compression coefficient and its determination under 1D condition, triaxial creep characteristics under drained and undrained conditions, long-term shear strength, and the creep characteristics under complex stress conditions are analyzed. The relevance of creep characteristics to strain-rate and strain relaxation characteristics under both 1D and 3D conditions is discussed. Finally, some new development of the creep characteristics of soft clay are presented in three aspects: the relevance of second compression coefficient to microstructure, accurate description of nonlinear creep, and the stress-dilatancy during drained and undrained creep.
