Tóm tắt

We examine the question of three-dimensional irregular waves acting on a vertical circular cylinder. Pilings in the form of circular cylinders are used as support elements for such hydrotechnical structures as offshore piers and stationary moorings. A theoretical-empirical approach to the solution of the problem for the action of swells was developed in [1]. The account for irregularity is based on the hypotheses which are adopted in spectral theory of waves. Examples are presented for particular cases of the sea-state spectral density.
