STUDIES ON WAVE PRESSURES AGAINST COASTAL DIKE

An experimental study of wave pressures against a coastal dike is reported, and the general characteristics of shock pressures exerted by a breaking wave, and wave pressures exerted by waves after breaking are elucidated. A general formula was obtained (which relates to wave pressure after breaking)which could be used to calculate wave pressure under a given condition. The formula of the deflection and moment in the front covering layer of wave action (considered as a beam on an elastic bed) was obtained and used to investigate the safety of the layer. Details are given of the experimental methods and apparatuses. Aspects of shock pressure exerted by breakers are reviewed and include characteristics of such shock pressure, the pressure exerted on a movable wall, the mechanism of the pressure, and the effect of dissipation of the pressure by means of armor blocks. Wave pressure after breaking on a vertical dike is described as well as on a sloping dike. The study of stress generated in front face by wave pressures covers both static load and dynamic load. Conclusions based on the study are listed.
