Abstract


A new stability formula for wave-dissipating concrete blocks covering horizontally composite breakwaters is proposed after reviewing the existing stability formulae and verified using experimental data. A method for estimating the expected value of the accumulated damage to wave-dissipating concrete blocks within their lifetime using the Monte Carlo simulation follows thereafter and the practicability of this method for reliability based design of wave-dissipating concrete blocks is shown.

Keywords


wave dissipation; concrete blocks; breakwater; composite breakwater
