State Index for Interpreting the State-Dependent Behavior of Granular Soil: A Review

State Index for Interpreting the State-Dependent Behavior of Granular Soil: A Review The strength and deformation behaviors of granular soil depend on the material state, i.e., density and pressure. To interpret such state-dependent behavior, different state indices were proposed in the past decades, which can be sorted into two categories: one based on a reference line, e.g., the critical state line (CSL), the other based on two or more reference lines, e.g., the CSL, the threshold void ratio line, the minimum or maximum void ratio line. Due to the different definitions, each state index has its merits and demerits, for example, the ones based on the vertical distance from the current state to the CSL are most applicable, when compared to those based on the horizontal distance that result in the difficulty for very loose soil to obtain a proper reference state at the CSL. In most cases, the state parameter ψ and its derivatives are suggested. In addition, the mathematical and physical aspects of the state dependence are also discussed, where the control of limiting dilatancy or dependence on the dissipated volumetric plastic work can be the underlying origin for the state dependence of granular soil. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Computational Methods in Engineering Springer Journals

Abstract

The strength and deformation behaviors of granular soil depend on the material state, i.e., density and pressure. To interpret such state-dependent behavior, different state indices were proposed in the past decades, which can be sorted into two categories: one based on a reference line, e.g., the critical state line (CSL), the other based on two or more reference lines, e.g., the CSL, the threshold void ratio line, the minimum or maximum void ratio line. Due to the different definitions, each state index has its merits and demerits, for example, the ones based on the vertical distance from the current state to the CSL are most applicable, when compared to those based on the horizontal distance that result in the difficulty for very loose soil to obtain a proper reference state at the CSL. In most cases, the state parameter ψ and its derivatives are suggested. In addition, the mathematical and physical aspects of the state dependence are also discussed, where the control of limiting dilatancy or dependence on the dissipated volumetric plastic work can be the underlying origin for the state dependence of granular soil.
