Abstract

This study carried out physical model experiments to identify the characteristics of horizontal wave loads on jacket foundations and investigate the variation patterns of wave loads under different wave conditions. A reliable and well-fitted prediction model was obtained by training a support vector machine （SVM） based on the physical model experimental dataset. Combined with the SVM prediction model, a global sensitivity analysis was performed using the Sobol method with respect to water depth, wave period and incident wave height, further clarifying the influence of each parameter on the horizontal wave loads of jacket foundations. It was found that among the parameters, incident wave height exerts the most significant effect on horizontal wave loads.
