Reinforced earth retaining walls
TLDR
In this paper, the results of analytical and laboratory studies on small reinforced earth retaining walls were compared to analytical solutions for wall failure by either pullout or breaking of the reinforcing elements, and found to be in reasonable agreement.Abstract:
Reinforced earth is a man-made earth fill in which thin bars, rods, fibers, or nets have been placed to improve the overall qualities of the soil This paper describes the results of analytical and laboratory studies on small reinforced earth retaining walls Experimental data were compared to analytical solutions for wall failure by either pullout or breaking of the reinforcing elements, and found to be in reasonable agreement Cost estimates for prototype structures suggest that the cost of reinforced earth could be as low as half the cost of other conventional earth retaining wallsread more

Static Response of Sands Reinforced with Randomly Distributed Fibers
Mohamad H. Maher,Donald H. Gray +1 more
TL;DR: In this article, a model based on a statistical theory of strength for composites was developed to predict the fiber contribution to strength under static loads, which significantly increase the ultimate strength and stiffness of sands.

Behavior of fabric- versus fiber-reinforced sand
Donald H. Gray,Talal Al-Refeai +1 more
TL;DR: In this paper, the authors compared the stress-strain response of a sand reinforced with continuous, oriented fabric layers as opposed to randomly distributed, discrete fibers, and found that both types of reinforcement improved strength, increased the axial strain at failure, and in most cases reduced post-peak loss of strength.

Behavior of granular soils reinforced with discrete randomly oriented inclusions
TL;DR: In this article, the load-deformation behavior of sand reinforced with discrete randomly oriented inclusions depends on particle shape and size of the sand, among other factors, on particle size and shape.
Journal ArticleDOI
Bearing capacity of reinforced sand subgrades
TL;DR: In this article, the effects of soil density and reinforcing strip length on the bearing capacity of reinforced and non-reinforcing sand were investigated, and the results showed that a significant increase in bearing capacity can be achieved at relative densities between 51 and 90% by the use of metal reinforcing strips.

Performance of Geosynthetic Reinforced Slopes at Failure
TL;DR: In this paper, the authors investigate the failure mechanisms of geosynthetic reinforced soil slopes and evaluate the assumptions in their design, and propose a new distribution of maximum reinforcement forces with depth, which is consistent with the failure mechanism observed in the models.
