A series of hydraulic model experiments were performed to verify the effect of armoring concrete blocks on the tsunami pressure reduction in the state of soliton fission. Applicable ranges for Tanimoto and modified Tanimoto formulas of wave pressure acting on a caisson have been determined in terms of the ratio of tsunami height for water depth. The estimation formula for the tsunami pressure reduction factor of the armoring blocks was proposed in the result of the comparison of tsunami force between the states without and with the armoring blocks. The calculated tsunami forces acting on the caisson armored with the blocks well agree with the corresponding experimental ones. The sufficient stability of the armoring blocks against the tsunamis has been confirmed by the experiments.
