Abstract

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