The analysis of stress distribution around a vertical pile in homogeneous soil, is extended to the case of nonhomogeneous soil. Solutions are presented for pile in "Gibson" soil where the modulus increases linearly with depth. The analysis consists in making use of the mindlin's equations for a point load in an elastic half space, but allowance has been made for the effects of varying soil moduli along the length of pile. Side shear distributions are calculated from compatibility of vertical displacements at the interface of pile and the soil for l/d ratios 25, 50, and 100. For these calculated side shear distributions, the stresses are evaluated as in the case of homogeneous soils. The results are compared with that of uniform soil and it is concluded that the nonhomogeniety factor has very little or no effect on the vertical stress when the pile behaves almost as rigid.
