Large circular caisson revetment is applicable to deep waters. Physical models are conducted to research the influence factors for wave forces on large circular caisson with connectors, the results show that the key factors are the position of wave wall on the structure, the height of wave wall, waves parameters, etc. on the basis of comparison of different theoretical methods of horizontal wave forces and experimental results, the modified Goda is given for total wave forces on large circular caisson revetment. The method can be used as reference for further research and engineering design.
