It is known that the distribution of active earth pressure against a translating rigid wall is not triangular but nonlinear, owing to arching effects in the backfill. In the present paper, a new formulation is proposed for calculating the active earth pressure on a rigid retaining wall undergoing horizontal translation. It takes into account the arching effects that occur in the backfill (or re...

Trench is connected to very narrow and deep excavation filled with bentonite suspension. This paper presents estimation of its stability in cohesive soil. The stability is assessed by two calculation methods. The first involves the equilibrium of forces acting on the rigid wedge. The second one includes numerical calculations conducted in Plaxis 3D Foundations. A few examples having different d...

This paper mainly studies the behavior of axisymmetric radial interaction between soil and structure under stress. Considering possible factors in interaction, such as arching effect caused by finite curvature, a simplified model is established. The influence curvature change on stress field, strain displacement field stress-strain relationship analyzed. Finally, status various their changes ar...

The face stability of shallow tunnels was investigated with small-scale model experiments at single gravity. Aim of the research was to detect the evolution of failure mechanisms in dense and loose soil samples with varying overburden above the tunnel. Moreover, the quality of proposed theoretical/numerical approaches for the determination of a necessary support pressure pf was assessed. The re...

Load transformation from the yielding part of soil to adjacent is known as arching effect, which plays an important role in design various geotechnical infrastructures. Terzaghi’s trapdoor test was milestone development theories on arching. The research earth pressure problem presented this paper using three-dimensional (3D) discrete element method (DEM). Five 3D models with different heights a...
