Vortex-induced Vibration of Single Pile in Marine Environment Considering Pile and Soil Interaction

摘要

In this paper the partial differential equations of transverse vortexinducedvibration of a single pile considering pile and soil interactionare established, in which the pile is simplified as Euler-Bernoulli beamand can be divide into two segments of pile. The upper segment of pileis excited by fluid forces and the lower segment of pile interacts withthe seabed which can be simplified as a viscoelastic medium. By meansof the methods of stiffness transmission, the equations can be solvedanalytically on the basis of Laplace transformation. By virtue ofMATLAB to solve the equation, the properties of vortex-inducedvibration of marine pile are illustrated.
