内容記述 | This paper deals with the current-induced motions of submerged tunnels i.e., instabilities that can arise for a submerged tunnel in a calm sea with a steady current. The dynamic response of smooth circular cylindrical models in unidirectional flow situations is investigated experimentally. The models were placed in a circulating water channel horizontally and normal to the direction of current flow. The two ends of the models were attached, using springs, to rigid supports. The traces of response vibrations for the inputs of current loading were recorded using video camera. The time histories of displacements along the horizontal and vertical direction were deduced from this data. Then, by Fourier analysis, the dominant frequencies of vibration were identified. The Strouhal number, which is a function of eddy-shedding frequency, was computed and is shown against Reynold's number. |
