ESTIMATING THE SLIDING DISTANCE OF COMPOSITE BREAKWATERS DUE TO WAVE FORCES INCLUSIVE OF IMPULSIVE FORCES

摘要

Estimating the sliding distance is essential in the future probabilistic design of caisson breakwaters. In this paper, characteristics of the sliding phenomena are described, and a method based on the equivalent sliding forces to calculate the sliding distance is proposed. This calculation method is applicable for both impulsive and ordinary wave forces considering the shear force at the bottom of the caisson.
