In order to study the force and displacement of bridge tower under wind, wave and current action, the elastic model of bridge tower structure was made. By the physical model test, the force, moment and displacement of the bridge tower top were measured under the different conditions. According to the test data, we found the resonance phenomenon could occur when the wave period is equal to or close to structural self vibration period. The force and moment increase with increasing the wave height and wind speed. There was some difference for the force, moment and displacement between the action of wind, wave and current separately and coupling action with wind, wave and current. Sometimes, the horizontal force under coupling action with wind, wave and current was more than the linear superposition value under action of wind, wave and current separately.
