PULL RESISTANCE AND INTERACTION OF EARTHWORK REINFORCEMENT AND SOIL

Results are presented of tests on different kinds of earthwork reinforcement to study pull resistance and soil-reinforcement interaction in reinforced earth. Three kinds of pull tests were conducted. Results indicate that the soil will not be significantly strained until a proportional limit is reached on a load-deformation curve. For the same surface area, bar-mesh reinforcement has nearly six times the pull resistance as that of flat steel-strip reinforcement. Bar-mesh reinforcement embedded in a dense cohesive soil exhibited greater pull resistance than that embedded in a less dense cohesionless soil. An increase in size of mesh opening will substantially reduce the pull resistance of the bar mesh. The minimum lengths of steel-strip reinforcement required for a low-height, reinforced earth wall was found to be at least 3.1 m (10 ft.).
