This relation is expressed as where is the shear strength, is the normal stress, is the intercept of the failure envelope with the axis, and is the slope of the failure envelope. The quantity is o…

Cohesive soil is hard to break up when dry, and exhibits significant cohesion … WebbFoundations on Non-Cohesive Soil of topsoil and silty clay overlying a considerable depth of medium dense sand. Average SPT values for the top metre of sand are in the range N = 22 − 41; a conservative average value of N = 25 will be assumed for determining the allow-able bearing pressure. A square base of 2 m × 2 m is initially assumed. From
