Abstract

In this work the cone model is used to analyze the dynamic behaviour of piles embedded in a soil layer, after introducing several mirror-image disks placed at the other side of the free surface and of the interface with bedrock. Principles of symmetry, anti-symmetry and superposition permit satisfaction of the boundary conditions. By comparison with rigorous solutions, the model exhibits adequate accuracy. The unavoidable loss of precision is fully compensated by simplicity in application. The calculated impedance function of the pile is used to analyze the pile group behaviour. 1 Introduction The cone model is a simple physical representation of the unbounded soil in a dynamic soil-structure interaction analysis. The cone model for translational mode of vibration was int
