Vertical Shear Loads on Nonmoving Walls. II: Applications
TLDR
In this paper, a simple design procedure is developed to consider vertical shear forces in non-moving retaining walls, and it is shown that significant economies can result from consideration of vertical hear forces.Abstract:
Massive concrete walls constructed on rock foundations, as well as other nonmoving retaining walls, are customarily designed for at-rest earth pressures. Vertical shear loads applied by the backfill are usually not considered in design of nonmoving walls, even though many field and laboratory measurements have shown that such loads exist. Vertical shear loads can be very beneficial for stability of retaining walls, because they provide restoring moments to counteract overturning moments from lateral earth loads. In this paper, model test results and case history data are reviewed, the results of finite-element calculations are presented, and a simple design procedure is developed. It is shown that significant economies can result from consideration of vertical shear forces in design of nonmoving retaining walls.read more

TL;DR: In this article, the authors present finite element analyses of earth pressures in narrow retaining walls for both at-rest and active conditions and show that due to arching effects and boundary constraint, the earth pressures decrease as the decrease of the wall aspect ratio.

Location of Failure Plane and Design Considerations for Narrow Geosynthetic Reinforced Soil Wall Systems
TL;DR: In this paper, a limit equilibrium analysis was performed to locate the critical failure plane in a Geosynthetic Reinforced Soil (GRS) wall for internal stability against pullout failure, and the results showed that the failure surface was formed partially through reinforced soil and partially along the interface between the GRS and the stable wall face.
