Behaviour of Surface Footing Resting on Reinforced Layered Soil

Abstract

AbstractThe work presented here includes laboratory model testing on surface footing placed on sand overlying crusher dust—a two layer system of soil. The experimental work has been conducted on unreinforced and geosynthetic reinforced soil at loose and medium dense state condition. The reinforcement has been used at interface to find its effect on bearing capacity compared to unreinforced state of soil. For loose state, a relative density of 35% has been chosen and for medium dense state, a relative density of 67% has been taken for both sand and crusher dust. The effect of relative density, effect of reinforcement layer on bearing capacity of surface footing has been studied.KeywordsModel testingSurface footingRelative densityCrusher dustGeosynthetic reinforcementBearing capacity
