The upper part of a pier wharf on the sea is usually made up of horizontal panel with both vertical and horizontal beams above the still water level.There have been quite a few theories and empirical studies that calculate the wave force on structures and propose many empirical equations concerning the wave force and corresponding pressure distribution.Nevertheless,due to the complex variables and changeable girder systems,it is necessary to determine the pop-up force and horizontal force on beam structures by physical model tests.The current study,by physical model tests,tests and calculates the wave force on the wharf platform,abutment and pile foundation under different situations of water level and waves at the petrochemical wharf,Haicang harbor,Xiamen.The test results have been adopted in practice by some design units.
