TL;DR: In this article, a numerical model was developed using finite element technique and the constitutive law of Mohr-Coulomb to simulate the case of a retaining wall partially supported by an embedded anchor plate in sand, and the results produced in this investigation showed that the passive earth pressure acting on anchor plates increases due to the increase of angle of shearing resistance and the overconsolidation ratio of sand.
Abstract: Passive earth pressure on embedded anchor plates constitutes a viable resisting force for the design of underground structures. In the current practice, these forces are empirically calculated, ignoring the effects of the depth of embedment and the level of consolidation of the surrounding soil, which takes place during plate installation on the in situ stress levels. Accordingly, wide discrepancies between predicted and measured pullout capacities of these plates were reported in the literature. Numerical model was developed using finite-element technique and the constitutive law of Mohr–Coulomb to simulate the case of a retaining wall partially supported by an embedded anchor plate in sand. The results produced in this investigation showed that the passive earth pressure acting on anchor plates increases due to the increase of angle of shearing resistance and the overconsolidation ratio of sand, and it decreases due to an increase of the embedment depth of anchor. Design theories were developed for the case of embedded anchor plate in overconsolidated sand. The theories developed will satisfy the design needed in terms of allowable pullout load and/or displacement.

TL;DR: In this article, the effects of earthquakes on cantilever retaining walls with liquefiable backfills were studied, including acceleration on the walls and in the backfill, static and excess pore pressures in the soil, and deflections and bending strains in the wall.

TL;DR: In this article, the effect of the distance between the two back-to-back geosynthetic-reinforced soil retaining walls of embankment approaching bridges on the internal and external stability was investigated under static conditions.
Abstract: Reinforced soil retaining walls with two opposite sides (back-to-back) are commonly used for embankments approaching bridges. This type of walls has complex geometry. The distance between two opposing walls is a key parameter used for determining the analysis methods in the federal highways administration guidelines. The objective of this research is to study under static conditions, the effect of the distance between the two back-to-back geosynthetic-reinforced soil retaining walls of embankment approaching bridges on the internal and external stability. Finite element method incorporated in the Plaxis software and analytical methods were used for this research. Parametric studies were carried out by varying the distance between side walls, to investigate their effects on the critical failure surface, the lateral earth pressure behind the reinforced zone, the wall displacement and on the required tensile strength of reinforcement.
