    Abstract
  • A theoretical study of diagonal wave for cesacting on partially perforated caisson breakwater with transver sewalls is performed based on the linear potential theory.An analytical method is developed to calculate the normal horizontal for cesacting on caissons,as well as the horizontal fo rcesacting on trans verse walls.The calculating results of wave forces for limited cases are the same to existing results in liter atures.The main influencing factors of wave forces are analyzed by means of numerical examples.The reduction of normal total horizontal forceacting on perforated caisson is mainly due to the upper perforat edsection of structure,where the influence of incident waves is significant.The incr easing sing lecaisson leng th is helpful to reducing total horizontal force acting on caissons.With larger incident wave angle or porous influence parameter modulus of caisson perforated front wall,the maximum total horizontal force acting on the transverse wall is larger than the corresponding normal total horizontal force acting on the caisson.At this time,the structural strength of transver sewalls should be enhanced.
