Based on the experiment carried out in this study, the effect of incoming wave direction on uplift force acting upon high piled wharf deck has been analyzed. The main influencing factors have been taken into account, which include the wave incident angle, wave types, period, wave height, height of wharf deck. For the regular and irregular wave, the testing results showed that the oblique wave incoming angle was the main influencing factor on uplift force in both with and without current circumstances. The current direction has effect on the decreasing trend of total uplift force. Moreover, the simplified formula on uplift force under oblique wave without current was proposed. The comparison between the observed and calculated results illustrated that the accuracy of the proposed formula can mainly satisfy the requirements in practice.
