TLDR
In this paper, an elastic overburden is proposed as a replacement for traditional tension cracks, and a statically determinate and solvable mathematical model for the limit equilibrium problem is established without considering the stress-strain relationship of the soil.Abstract:
The slip-line method is commonly used to solve the limit earth pressure on retaining walls, but to date there are still a number of problems that have not yet been solved. Based on limit equilibrium theory, the backfill is considered to be an ideal elastic-plastic material, which obeys the Mohr–Coulomb yield criterion, and is assumed to be an ideal continuous medium that is isotropic, homogeneous and incompressible (or non-expansive). Various factors of influence are considered in the calculation model. An elastic overburden is proposed as a replacement for traditional tension cracks. A new concept – stress singularity – and its stress boundary conditions are introduced, and a statically determinate and solvable mathematical model for the limit equilibrium problem is established without considering the stress–strain relationship of the soil. The slip-line stress field in the plastic zone of the backfill is solved by using the slip-line method, following which the active earth pressure on retaining walls a...read more

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.
