TL;DR: In this article, the authors present experimental results obtained for the distribution of the active stresses due to a sand backfill behind a rigid wall rotating about the top of the wall, and compare the active earth pressure distributions for three different wall movement modes: rotation about top, rotation about heel, and translation.
Abstract: In this paper the writers first present experimental results obtained for the distribution of the active stresses due to a sand backfill behind a rigid wall rotating about the top. The experimental evidence shows that the stress distribution is nonlinear and that, due to arching, the stress near the top of the wall increases beyond the level of the at‐rest stress. Consequently, the point of application of the lateral thrust is much higher than one‐third from the wall base. Arching effects increase with increasing soil density. Secondly, comparisons of the active earth pressure distributions are made for three different wall movement modes: (1) Rotation about top; (2) rotation about heel; and (3) translation. Total active resultant forces and the points of application of these forces are summarized.

TL;DR: In this article, a two-dimensional disk-based implementation of the Distinct Element Method (DEM) is validated using numerical simulations of standard geotechnical laboratory tests, such as one-dimensional compression, direct simple shear and triaxial tests.
Abstract: The Distinct Element Method (DEM), a numerical technique which treats soil as a discrete assemblage of particles, can be useful when local yield, bifurcation behavior or nonlinear soil‐structure interaction occurs. A two‐dimensional disk‐based implementation of the DEM is validated using numerical simulations of standard geotechnical laboratory tests, such as one‐dimensional compression, direct simple shear and triaxial tests. These test results indicate that the two‐dimensional DEM can simulate realistic nonlinear, stress history‐dependent soil behavior appropriately when individual particle rotation is inhibited.Modeling of large‐scale problems is accomplished by constructing a reduced‐scale model, then applying the geotechnical centrifuge scaling relationships in order to reduce the number of particles simulated and to ensure stress‐strain‐strength similitude between the model and prototype. Full‐scale simulations, including bearing capacity and lateral earth pressure tests, indicate that the DEM can a...

TL;DR: In this paper, a small-scale tunnel model in a geotechnical centrifuge was used to investigate the stability of the face stability of a tunnel in the case of failure mechanism, surface settlement, and stress acting at tunnel face.
Abstract: This paper is an investigation of face stability on a small-scale tunnel model in a geotechnical centrifuge. By making use of symmetry, half of the tunnel cross section was considered. The support at excavation face was provided by a piston, which was adjusted during flight. Some aspects on the collapse at tunnel face are investigated for different overburden pressures: failure mechanism, surface settlement, stress acting at tunnel face, and the required face support counteracting the earth pressure. Ground deformation was observed through a transparent wall and measured by digital image correlation. The results from centrifuge model tests were compared with theoretical models.

TL;DR: In this article, the authors used the pseudo-dynamic method to compute the distribution of seismic active earth pressure on a rigid retaining wall supporting cohesionless backfill in more realistic manner by considering time and phase difference within the backfill.
Abstract: Knowledge of seismic active earth pressure behind rigid retaining wall is very important in the design of retaining wall in earthquake prone region. Commonly used Mononobe-Okabe method considers pseudo-static approach, which gives the linear distribution of seismic earth pressure in an approximate way. In this paper, the pseudo-dynamic method is used to compute the distribution of seismic active earth pressure on a rigid retaining wall supporting cohesionless backfill in more realistic manner by considering time and phase difference within the backfill. Planar rupture surface is considered in the analysis. Effects of a wide range of parameters like wall friction angle, soil friction angle, shear wave velocity, primary wave velocity and horizontal and vertical seismic accelerations on seismic active earth pressure have been studied. Results are provided in tabular and graphical non-dimensional form with a comparison to pseudo-static method to highlight the realistic non-linearity of seismic active earth pressures distribution.
