Ultimate bearing capacity of strip foundation on geogrid-reinforced clay slope

Laboratory model results for the ultimate bearing capacity of a surface strip foundation on a saturated slope reinforced with geogrid layers are presented. The angle of the slope with the horizontal was varied from 35° to 50°.A biaxial geogrid was used as reinforcement for all of the model tests. The location of the top geogrid layer with respect to the bottom of the foundation, center-to-center spacing of the geogrid layer, and depth of geogrid reinforcement were varied. Based on the model test results a preliminary outline for estimating the ultimate bearing capacity is presented.
