Abstract

The effect of reinforcing a sandy slope with geogrid on lateral resistance of a single pile located near a slope is studied by small scale model tests. Therefore, a broad series of conditions including unreinforced cases was tested by varying parameters such as: arrangement of geogrid reinforcements, pile distance from the slope crest, relative density of sand, angle of the slope, embedded length, shaft roughness and cross section of pile. The results indicate that improvement in lateral resistance of the pile intensively depends on the arrangement of geogrid reinforcements. The optimum length and width values of geogrid layers (i.e. the one leading maximum lateral resistance of a single pile) were 31d and 24.6d (d=pile diameter) and 2.82d, 1.64d for the depth of first layer and spacing between geogrid layers respectively.
