Armor block stability for the mound of sloping breakwaters was examined by 2-D model tests. Damage patterns of armor blocks at the mound berm were reproduced by wave force tests. By the action of breaking wave, armor blocks at the offshore side of mound were uplifted by the vertical wave force, and overturned by. the wave induced flow. Based on the stability test results, the stability number of armor blocks was formulated as the function of relative depth, relative mound height and sea bottom slope. Furthermore, the relationship between the damage level and the number of wave action was shown for storm wave conditions exceeding the design wave height.
