Effect of Dilatancy Angle on Bearing Capacity.
In: 50th Indian Geotechnical Conference, 17-19 Dec, 2015, Pune, India.
Abstract
In Mohr-Coulomb failure criterion, the angle of shearing resistance of soil is assumed to be constant along the slip plane. However, over the second half of the last century, it is well recognized that the dilatancy angle influences the shear strength of sand. Many researchers have proposed correlations between the angle of shearing resistance at peak state in terms of intrinsic soil variables and soil state variables. Studies on the effect of dilatancy angle of soil, ψ, on the load-settlement response of a strip footing are available in the literature. However, in most of these studies, ψ equal to zero or equal to angle of shearing resistance of soil, is assumed, and only limited studies are available to predict the load-settlement response of strip footing when the dilatancy angle of sand lies between zero and In the present study, the effect of dilatancy angle of sand on the loadsettlement response of a rigid strip footing resting on sand and on the formation of slip planes is studied by varying the dilatancy angle ranging from zero to the angle of shearing resistance of soil (i.e., ψ =0 to )
