Liehong Ju, Peng Li, Ji hau Yang

Abstract


Extensive researches have been done for the interaction between open-type pile foundation structure and waves, including uplift force of wharf deck, horizontal force of structure and wave transmission behind breakwaters, among which wave transmission is mainly discussed in this paper. The wave transmission through a single immersed vertical barrier is analyzed by use of the physical model experiment; and an approximate formula to calculate the coefficient of wave transmission through a barrier is presented. Finally the wave damping effect of twin barriers is tested and analyzed.

Keywords
