Abstract

The upper part of a pier wharf on the sea is usually made up of the horizontal panels with both longitudinal and transverse beams above the still water level. To estimate the wave force on the structures, many scholars have conducted theoretical and experimental researches, and proposed a lot of empirical equations concerning the wave force and corresponding pressure distribution. Nevertheless, due to the complex factors and changeable girder systems, the generation mechanism of wave uplifting forces has not been fully understood so far, and the discreteness and limitations of experimental data lead to vastly difference between various empirical formulas, which causes that the calculated wave forces using different formulas differ by ten times. Therefore, it is necessary to determine wave the uplifting force and horizontal force on girder structures by conducting physical model experiments. In the present study, the physical model experiments with a scale of 1:40 are used to measure the wave forces on the wharf platform, abutment and pile foundations under different combinations of water level and waves at Petrochemical Wharf, Haicang Harbor, Xiamen. The experiment results have already been adopted in practice by some design institutes.
