STRESS IN SOIL AROUND VERTICAL COMPRESSIBLE PILES

A method of analysing vertical stress by obtaining the side shear distribution using linear elastic theory. The influence of a pile's compressibility and L/d ratio on its stress distribution when mu equals 0.5 have been studied the difference between rigid and very flexible piles. The side shear distribution thus obtained for a given ratio is divided into uniform and linear variations and is finally summed up to get the net stresses. The double integration of the Mindlin's equation involved in this step-by-step procedure is solved partly analytically and partly numerically by computer, using Gauss Quadrature formulas. Although analysis is here confined to vertical stresses, other stresses could be evaluated with this method. Stress coefficient tables covering a wide range of stiffness factors from very flexible to very rigid are presented for selected ratios of pile length to pile depth and of radial distance to pile length.
