Experimental and Theoretical Investigations on Active Earth Pressure Distributions behind Rigid Retaining Walls with Narrow Backfill under a Translational Mode
TLDR
The existing earth pressure theories, such as Rankine's theory and Coulomb's theory, adopt planar slip surfaces to establish force equilibrium equations as mentioned in this paper for retaining walls, especially fo...Abstract:

Towards an improved analytical framework to estimate active earth pressure in narrow c – ϕ soils behind rotating walls about the base
TL;DR: In this paper, an analytical framework using arched differential element method is presented with overall considerations of soil cohesion, soil arching effect, shearing forces between adjacent elements and the studied failure mechanism.

Soil deformation measurement using particle image velocimetry (PIV) and photogrammetry
TL;DR: A deformation measurement system based on particle image velocimetry (PIV) and close-range photogrammetry has been developed for use in geotechnical testing as mentioned in this paper.

Coefficient of Earth Pressure at Rest
TL;DR: In this paper, the authors revisited the Jaky coefficient of earth pressure at rest, K0, and demonstrated that this coefficient was derived from an analysis of the stress state in a sand prism that yields an unrealistic stress field.

The Arch in Soil Arching
TL;DR: In this article, a catenary arch is used to describe the path of the minor principal stress, which is complementary to a structural arch and dips downward instead of upward if supportive.

Micromechanical features of granular assemblies with planar elliptical particles
TL;DR: In this article, the authors present the results of numerical simulations of planar assemblies of elliptical particles and identify qualitative features of these systems that are similar to real sand behaviour that are identified a...
