Abstract

This paper presents a novel numerical-analytical method for dynamics of piles embedded in non-homogeneous transversely isotropic soils. In the method proposed, the piles are modelled using beam-column elements, while a new type of elements called radiation discs are defined at the nodal points of the elements to simulate the wave propagation through the non-homogeneous soil medium. By using radiation discs, the discretisation is only required along the length of piles, while discretisation of surrounding medium, top free surface boundary, and cross sections of piles are avoided. Numerical results are presented and the effect of soil non-homogeneity on lateral compliances of piles and pile groups is particularly emphasised.
