The effect of displacement speed of rigid retaining walls on failure of analogical material by active earth pressure

Abstract

This paper illustrated the physical modeling of the phenomenon of Active Earth Pressure and kinetics of rupture in the granular soils. Better, understand the phenomenon of Active Earth Pressure and mechanisms of failure behind the retaining walls will contribute to better conceiving them and will make claims less damaging. The exploitation of a small-scale model filled with Schneebeli material;light two-dimensional material simulating granular non-cohesive soil, allowed tests realization of Active Earth Pressure by moving the mobile wall of the device towards the outside of two-dimensional material. The evolution of the shear bands has highlighted the locations of the deformations. The results showed that the wall's speed of movement influences the failure mechanism and is proportional to the disturbance of the granular soil. In perspective, it would be judicious to explore the failure on real soil reinforced by recycled materials.
