CALCULATION THE REQUIRED MASS FOR STABILITY OF THE BLOCK ON THE STEEP BOTTOM OF THE SEA

Abstract

  The present study understands the behavior of the foot protection concrete block of the plunging breaker on the steep coast of bottom slope 1/5 through the hydraulic model experiment and we propose the method of calculating the required mass of the foot protection concrete block of the plunging breaker. At first, we confirmed that the movement and scattering of the block is triggered by sliding by the wave force. The next, we calculated hydraulic quantity and evaluated stability for the sliding of the block, in the CADMAS-SURF. In the study, we show that the required mass for stability of the block is calculated with good precision in the CADMAS-SURF.
