The effective reuse and recycling of granular waste materials, namely coal wash (CW) and Basic Oxygen Steel slag (BOS), is economically beneficial and environmentally sustainable. Nevertheless, due to the heterogeneity of these granular waste materials, their ultimate adoption as structural fills must be supported by constitutive relationships capable of accurately describing the stress-strain behaviour under representative field loading conditions. In this paper, a critical-state-surface generalised-plasticity model is presented and its predictive capability using a single set of soil parameters is demonstrated for drained triaxial compression tests.

“…The SANISAND constitutive model has been specifically tested for its ability to reproduce a series of monotonic and cyclic tests on Toyoura sand [31,32], Nevada sand [33], and Sacramento river sand [34] in a wide range of relative densities and confining pressures and in different drainage conditions. The 14 material parameters required by the model for these sands are listed in Table 2; they are divided into different groups according to the particular role they play.…”

“…10 and 11 compare the experimental data [32] and model simulations for drained constant-p cyclic triaxial tests on isotropically consolidated loose and dense samples of Toyoura sand. In these tests the amplitude of shear strain (g ¼ e a Àe r , as defined in [32]) has been increased with cyclic loading. Accumulation of compressive volumetric strain with cyclic loading can be observed in Fig.…”

a b s t r a c tTo predict the earthquake response of saturated porous media it is essential to correctly simulate the generation, redistribution, and dissipation of excess pore water pressure during and after earthquake shaking. To this end, a reliable numerical tool requires a dynamic, fully coupled formulation for solidfluid interaction and a versatile constitutive model. Presented in this paper is a 3D finite element framework that has been developed and utilized for this purpose. The framework employs fully coupled dynamic field equations with a u-p-U formulation for simulation of pore fluid and solid skeleton interaction and a SANISAND constitutive model for response of solid skeleton. After a detailed verification and validation of the formulation and implementation of the developed numerical tool, it is employed in the seismic response of saturated porous media. The study includes examination of the mechanism of propagation of the earthquake-induced shear waves and liquefaction phenomenon in uniform and layered profiles of saturated sand deposits.

“…Change of volumetric strain in different stage of loading can be described by the stress-dilatancy relationship, which relates the dilatancy ratio (-dε d vol /dγ p vol ) to the stress ratio (τ/p') [17,18]. For the case of torsional shear [19] proposed the following empirical linear stressdilatancy relationship: (8) where N d and C d are the gradient and the intercept in the plot (-dε d vol /dγ p vol ) vs. (τ/p'), respectively.…”
