An attempt has been made to evaluate the stresses by obtaining the side shear distribution using linear elastic tehroy as suggested by Mattes and Poulos. The influence of the compressibility and L/d ratio of the pile on the stress distribution have been studied for μ = 0.5, to show the difference between a very flexible and a rigid pile. The side shear distribution thus obtained for a particular ratio of L/d and compressibility of the pile is divided into uniform and linear variations and is finally summed up, to get the net stresses. This is a step-by-step procedure, and the double integration of the Mindlin.s equation involved is solved partly analytically and partly numerically in a computer, using Gauss Quadrature formulas. The analysis is confined to vertical stress, although other stresses could be evaluated by the same technique.
