Stresses in Soil around Vertical Compressible Piles

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.
