A contribution to the study of axially loaded pile foundations

A study of some of the major parameters governing behaviour of pile foundations is described. The problems of: (a) the load-displacement characteristics of single piles (b) the load-displacement characteristics of free-standing pile groups with any arbitrary spacing, (c) the interaction between a pile cap and its group, (d) the stresses and pore water pressure around a driven pile, are analysed by assuming an elastic ideally plastic model behaviour for soils. The elastic analysis is made by developing an integral equation method based on the theory of multidimensional singular integral equations. An algorithm for the solution of the singular integral equations is described. The computational work involved has been greatly reduced by choosing for singular solution of the integral equation, the kernel function due to a point load within an elastic half space. Numerical solutions of the closely related topic of static response of buried rigid discs of arbitrary shape within a finite elastic layer are also obtained. The behaviour of a driven pile is analysed and an equation is developed for predicting the changes in the pore water pressures due to the driven pile.

Abstract

A study of some of the major parameters governing behaviour of pile foundations is described. The problems of: (a) the load-displacement characteristics of single piles (b) the load-displacement characteristics of free-standing pile groups with any arbitrary spacing, (c) the interaction between a pile cap and its group, (d) the stresses and pore water pressure around a driven pile, are analysed by assuming an elastic ideally plastic model behaviour for soils. The elastic analysis is made by developing an integral equation method based on the theory of multidimensional singular integral equations. An algorithm for the solution of the singular integral equations is described. The computational work involved has been greatly reduced by choosing for singular solution of the integral equation, the kernel function due to a point load within an elastic half space. Numerical solutions of the closely related topic of static response of buried rigid discs of arbitrary shape within a finite elastic layer are also obtained. The behaviour of a driven pile is analysed and an equation is developed for predicting the changes in the pore water pressures due to the driven pile. The time dependent response of the pile resulting from the dissipation of these pore water pressures is then examined. The theoretical solutions have been compared with published laboratory and field data with reasonable agreement obtained.
