Abstract
Sea level change and global warming may cause increasing of external forces due to tides, currents and waves acting on breakwaters. Increase of breakwater weights or additional weight behind of present breakwaters become necessary against such external forces. A counter-weight block is newly developed to increase the resistance against horizontal sliding of breakwaters located at entrance of harbors. In the paper, a physical experiment is carried out to evaluate the friction factor of the counter-weight blocks and to compare with a normal type flat armor concrete block. The friction factor of counter-weight block with rubbles inside the center hole becomes larger than that of the normal one. A simple expectation formula calculating the effect of counter-weight block is proposed according to the experimental result.
