Dynamic Behaviour of Pile Foundations in Layered Soil Half-Space Using Cone Method
The dynamic behaviour of pile foundations embedded in a horizontally stratified soil profile is investigated using the Cone method, which applies only for shallow foundations. In this paper dynamic impedance functions have been generated for several cases using an enhanced cone frustum approach which deals with the drawback of negative damping in the current approach. The frequency domain approach can be implemented in systems modelled using the spectral elements. Comparison with the coupled Finite Element-Boundary Element (FE-BE) method shows a good correlation with the proposed method which does not use transformation to the wave-number domain.
