It is important to specify most dominant design parameters affecting safety of structures and to improve estimated accuracy of them in order to promote construction cost reduction through the reliability-based design. In this study, the dominant parameters for stability against sliding, overturning, and foundation failure of caisson-type breakwaters are specified by using safety index and sensitivity factor with FORM (First-Order Reliability Method). Moreover, correlations among failure modes in present design sections were described.
