A STUDY ON SIMPLE ESTIMATION METHOD OF DEFORMATION OF COMPOSITE CAISSON TYPE BREAKWATER USING HYDRAULIC MODEL EXPERIMENT RESULT

Abstract

 Evaluation of deformation is important for the performance-based design of caisson type composite breakwaters. However, evaluation method of deformation except for sliding failure mode has not been established yet.
 This paper presents a simple estimation method of deformation of breakwaters of the hydraulic model experiment results. Authors applied the regression analysis using a past hydraulic model experiment results and proposed a simple estimation equations for penetration angle, apparent friction coefficient, and rotation angle of caisson. It was shown that estimated deformation of breakwaters by the proposed method is in good agreement with that by the past hydraulic model experiment result.
