Soil-reinforcement interaction: Stress regime evolution in geosynthetic-reinforced soils
https://orcid.org/0000-0002-9335-7847
Abstract Understanding the stress regime that develops in the vicinity of reinforcements in reinforced soil masses may prove crucial to understanding, quantifying, and modeling the behavior of a reinforced soil structures. This paper presents analyses conducted to describe the evolution of stress and strain fields in a reinforced soil unit cell, which occur as shear stresses are induced at the soil-reinforcement interface. The analyses were carried out based on thorough measurements obtained when conducting soil-reinforcement interaction tests using a new large-scale device developed to specifically assess geosynthetic-reinforced soil behavior considering varying reinforcement vertical spacings. These experiments involved testing a geosynthetic-reinforced mass with three reinforcement layers: an actively tensioned layer and two passively tensioned neighboring layers. Shear stresses from the actively tensioned reinforcement were conveyed to the passively tensioned reinforcement layers through the intermediate soil medium. The experimental measurements considered in the analyses presented herein include tensile strains developed in the reinforcement layers and the displacement field of soil particles adjacent to the reinforcement layers. The analyses provided insights into the lateral confining effect of geosynthetic reinforcements on reinforced soils. It was concluded that the change in the lateral earth pressure increases with increasing reinforcement tensile strain and reinforcement vertical spacing, and it decreases with increasing vertical stress.
Highlights Soil stresses evolve in the vicinity of reinforcements in reinforced soil masses. Understanding the evolution of soil stresses between reinforcements provides insights into the lateral confining effect of reinforcements on soils. The change in the lateral earth pressure increases with increasing reinforcement tensile strain and reinforcement vertical spacing. The change in lateral earth pressure per unit change in vertical stress decreases with increasing vertical stress.
