Experimental Study for Irregular Wave Uplift Force on Upper-Structure of Offshore High-Piled Wharf under Wave-Current Interaction

Abstract:

This paper studies uplift force on upper-structure of offshore high-pile wharf under interaction of wave and current through indoor wave physical model test. The research takes various wave elements, wave incident angle and the angle of wave and current and other factors into consideration and launches a series of test to analyze the influence of different factors on wave uplift force. The research result shows that with the increase of wave incident angle the wave action width decreases which results in the gradually decrease of wave uplift force. When wave and current are in the same direction, the total wave uplift force decrease; when wave and current are in opposite directions which leads to the reduce of wave incident angle while results in the increase of wave height, the total wave uplift force increases; when wave obliquely incidents with the action of current, the factors influencing uplift force consist of wave obliquely incident action and current.
