Abstract

A state space solution for a partially embedded pile under combined lateral and vertical loads is developed. Two sets of state space equations above and below ground are deduced from Euler-Bernoulli’s and Winkler’s linear elastic foundation beam theories respectively, in which the coefficient of sub-grade reaction is defined by a three parameter model. Two pile shafts above and below ground are divided into uniform sub-sections by means of sub-section approximation method in order to make the above nonlinear state space equations become linear. The expressions of bending deformations and internal forces for all the sub-sections are deduced by virtue of matrix theory, boundary conditions, continuity-smooth conditions at the interface between two adjacent sub-sections. Computational results for a specific pile under specified lateral and vertical loads reveal that the present solution agrees well with existing semi-analytical one, and has higher convergence and accuracy.
