Simple and Unified Modelong of Time-Dependent Behavior for Various Geomaterials
A simple model to describe time-dependent behavior for various kinds of soils is presented.The present model can describe various time-dependent behaviors not only of normally consolidated soil but also of over consolidated and naturally deposited soils in the same manner without violating the objectivities.To consider the influence of over consolidation,the subloading surface concept defines a state variable (p) which represents the influence of density.To describe the behavior of naturally deposited soil,another state variableω,which represents the bonding effect,is introduced.The validity of the present models is verified using various kinds of simulations of time-dependent behavior in one-dimensional and three-dimensional conditions.
