Abstract :
In this paper a laboratory study has been carried out on the effect of changing the type of soil filling cylindrical reinforcing elements from
SM to GM on behavior of sandy soil. In this study the primary tests for evaluation of the impact of reinforced sand and gravel columns with
diameters of 5 cm and heights of 15 cm subjected to vertical stresses of 50, 100, and 150 KPa were carried out in a large-scale direct shear
apparatus (300×300×150 mm). Results showed that the shear stress and settlement of the reinforced sample with geogrid and a gravel
column increases by 45.4% and decreases by 23.9% respectively compared to the non-reinforced sample.
