Bearing Capacity of Strip Foundation on Geogrid-Reinforced Clay
Laboratory model test results are presented for the ultimate bearing capacity of a strip foundation supported by a saturated clay layer reinforced by layers of geogrid. The tests were conducted in one type of clay. The average moisture content of the clay was varied, yielding varying undrained shear strengths. Laboratory tests were conducted to determine the critical nondimensional values for the depth and width of the geogrid reinforcement layers and also the location of the first layer of geogrid with respect to the bottom of the foundation to obtain the maximum possible bearing capacity ratio.
