BEARING CAPACITY OF STRIP FOOTINGS ON PARTLY SATURATED SOILS

Authors analyze ultimate bearing capacity, assuming the soil to be rigid-plastic at failure, and using the pore pressure coefficients and effective stress concepts introduced by Skempton and Bishop. A rough strip footing is assumed with an elastic wedge of soil formed beneath the foundation at the instant of failure. The solution of the bearing-capacity problem is obtained by the method of characteristics. A large number of curves are presented showing the influences of pore-pressure coefficients and pore air pressure on the values of the bearing capacity factors N sub C, N sub Y and N sub q, and also the influence of these parameters on the shape of the slip lines. It is concluded that the ultimate bearing capacity is considerably affected by degree of saturation and by initial pore pressures. Paper is recommended for scientists and soil engineers dealing with bearing-capacity problems in partly saturated soils. /Author/
