Embedded strip footing in a geotextile-reinforced sand slope

Emmanuel Baah-Frempong, Sanjay Kumar Shukla
This paper presents experimental and numerical investigations of dense sand slopes supporting an embedded strip footing, considering both unreinforced and geotextile-reinforced cases. The effect of footing location, defined in terms of embedment depth D and edge distance e, on the bearing capacity of the footing was investigated. The results show that the bearing capacity of the footing increases with an increase in D and e. The inclusion of one layer of geotextile reinforcement in the dense sand slope further increases the bearing capacity, and this benefit has been expressed in terms of BCRu, which is defined as the ratio of ultimate bearing capacity for reinforced case to ultimate bearing capacity for unreinforced case. The maximum value of BCRu≈2.5-3 is observed for D/B = 0 and e/B = 0 where B is the width of the footing, while the minimum value of BCRu≈1.5 has been obtained for D/B = 1 and e/B = 3 , as considered in the present study.
