Abstract
This paper is prepared to propose fundamental points to be considered for design of caisson walls against breaking impulsive wave pressures. This have been obtained through field surveys of damages which have occurred over the past 30 years due to breaking impulsive wave pressures, and through a analysis of extent, characteristic, cause etc. of such damages. It was found, as a result of our study, that there is a relationship between actual failure level and cracking moment and safety factor (ratio: initial cracking moment against actual bending moment), and that this brings about a possibility to establish a practical design method, applying Goda pressure formula in consideration of the impulsive pressure coefficient (Takahashi et al.) 3) .
