"p-y" curves for piles in radially inhomogeneous soil
"p-y" curves for piles in radially inhomogeneous soil
“p-y” curves are used to simplify the pile response of laterally loaded piles at any given depth by describing the applied lateral soil reaction as a function of the lateral displacement. Simple analytical solutions in two-dimensions for system stiffness are available by modelling a segment of the pile surrounded by an annular zone of linear-elastic soil. Current solutions assume homogeneous soil conditions. However, installation of a bored pile in clay would result in a region of softened material immediately surrounding the pile-soil interface, which can be modelled using a function describing the variation of shear modulus with distance from the pile. Such functions are available in the literature using linear and power-law variations. This paper derives an improved solution for the system stiffness considering the effects of pile installation. The previously discussed annular zone of soil is split into multiple rings with each able to define an independent shear modulus. A solution for the overall system stiffness is provided. Three-dimensional and parameter effects are discussed.

Abstract
“p-y” curves are used to simplify the pile response of laterally loaded piles at any given depth by describing the applied lateral soil reaction as a function of the lateral displacement. Simple analytical solutions in two-dimensions for system stiffness are available by modelling a segment of the pile surrounded by an annular zone of linear-elastic soil. Current solutions assume homogeneous soil conditions. However, installation of a bored pile in clay would result in a region of softened material immediately surrounding the pile-soil interface, which can be modelled using a function describing the variation of shear modulus with distance from the pile. Such functions are available in the literature using linear and power-law variations. This paper derives an improved solution for the system stiffness considering the effects of pile installation. The previously discussed annular zone of soil is split into multiple rings with each able to define an independent shear modulus. A solution for the overall system stiffness is provided. Three-dimensional and parameter effects are discussed.
