Arching effect on lateral pressure of confined granular material: numerical and theoretical analysis
TL;DR: In this paper, the lateral pressure of confined granular material is studied through the numerical and theoretical analysis, and the transition of the lateral force can be divided into two stages based on the magnitudes of wall movements, at which the interface friction angle and internal friction angle are fully mobilized.

A finite element performance-based approach to correlate movement of a rigid retaining wall with seismic earth pressure
Junied Bakr,Syed Mohd Ahmad +1 more
TL;DR: In this paper, a finite element model-based investigation and development of a relationship between the seismic active and passive earth pressure and the movement of a rigid retaining wall is presented, where a hardening soil with small strain model with consideration of Rayleigh damping has been adopted for modelling soil.

Three-dimensional active earth pressure coefficients by upper bound numerical limit analysis
TL;DR: In this paper, a 3D numerical implementation of the limit analysis upper bound theorem is used to determine active horizontal earth pressure coefficients, and the ratio between the 3D and 2D horizontal active earth pressure coefficient for both soil weight and surcharge is shown and found to be almost independent of the soil-to-wall friction ratio.

Active Earth Thrust Considering Tension Crack, Pore-water Pressure and Soil Nonlinearity
Zheng-Wei Li,Xiao-li Yang +1 more
TL;DR: In this article, the authors developed a kinematical approach to analyze how the active earth thrust is influenced by tension cracks and pore-water pressure, using the power-law nonlinear yield criterion.

Discretization-based kinematical analysis of three-dimensional seismic active earth pressures under nonlinear failure criterion
TL;DR: In this article, a discretized three-dimensional failure mechanism of sloping backfills is proposed to estimate the seismic active earth pressure coefficient under nonlinear failure criterion, where the normality condition is strictly satisfied in the generation of the end cap.

A hypoplastic relation for granular materials with a predefined limit state surface
TL;DR: In this article, Wu et al. developed a hypoplastic theory for granular materials developed by Gudehus and Bauer and discussed the suitability of the Matsuoka/Nakai criterion for critical states.
A Comprehensive constitutive equation for granular materials
TL;DR: In this paper, a constitutive equation for describing changes of states of granular materials which are sufficiently characterized by the void ratio and the stress tensor is proposed, which may be considered as an extension of the Critical State concept.

A numerical study of the effects of wall deformation on earth pressures
David M. Potts,Andy Fourie +1 more
TL;DR: In this paper, the effect of wall deformation on the generation of earth pressure was investigated using the finite element method, and it was shown that the distribution of the earth pressure is highly dependent on the assumed mode of deformation.
