A constitutive model based on the critical state concept and viscoplasticity is developed. The
model is capable of predicting primary and secondary compression, including the effects of …

In the complex soil stress state encountered in the braced excavation, different stress states
lead to diversion of principal stress directions. The stress-induced anisotropy is introduced to …

The initial stresses existing in the natural ground are anisotropic in the sense that the vertical
stress is typically larger than the lateral stresses. The construction activities, such as …

ABSTRACT A generalized three~ dimensional constitutive model for isotropic cohesive
soils, based on the concept of the bounding surface in stress space, is developed within the …

This paper develops a bounding surface elasto-viscoplasticity model to consider the viscous
behaviors of saturated clays. Consisting of a bounding surface, a dynamic loading surface …

The objectives of this study are to investigate and evaluate the benefits of inclusion of
geogrids in two types of geosynthetic reinforced soil/aggregate structures—reinforced soil …

An anisotropic time-dependent bounding surface model for clays is developed by
generalizing a previous time-independent model that adopts a flexible bounding surface. It …

The equations governing the dynamic behavior of saturated porous media as well as a finite
element spatial discretization of these equations are summarized. A three‐parameter time …

A study of the response time of miniature pore pressure transducers embedded in clay soils
is presented. The highly nonuniform pore pressure distributions around the transducers due …

A numerical implementation of the “bounding surface plasticity” model for cohesive soils is
described. An adaptive multistep integration procedure is used in conjunction with local …
