Abstract
Level-1 reliability-based design method (partial factor design method) is recommended for standard structural design method. This study conducts the code calibration of partial factors for stability against sliding, overturning, foundation failure of gravity-type breakwaters (five structural types: caisson-type composite breakwaters, breakwaters covered with wave-dissipating blocks, three gravity-type special breakwaters). Setting the current mean safety levels as target values and using sensitivity factors, we decided the appropriate values of partial factors. Moreover, we showed that the established level-1 design method enables more reasonable design than current method.
