It is necessary to maintain wave dissipating blocks for the armor of breakwaters properly because settlement of blocks often causes large disaster. Therefore, clarification of correlation between block settlement and breakwater displacement is important for the establishment of effective maintenance strategy. Previous study discusses maintenance strategy of breakwaters armored with wave dissipating blocks on the assumption of uniform displacement of breakwaters, however, uneven displacement of breakwaters is observed in field. This study considers uneven displacement of breakwaters and discusses the maintenance criteria for the minimum repair cost during working life of breakwaters.
