摘要：A bridge is partially or entirely submerged when subjected to flood or huge wave striking. The wave force acting on its main girders is time-varying hydrodynamic load. Several of the current international and domestic calculation methods of horizontal wave forces acting on main girders of bridge are analyzed, and effects on horizontal wave forces of the submergence degree and the shape of main girders are discussed. The regularities of distribution of C-D of main girders are summarized. Results of the study offer a calculation method of wave loads on bridges to the actual engineering design; how to estimate the wave forces acting on the bridge was discussed. The calculation and design method for reference is proposed.
