抛石潜堤消浪特性试验研究

Submerged breakwater is the common wave absorbing structures in coastal engineering and port projects. It is play a very important role in the protection of the coastline as well as the job security from the wave attack. The paper studies upon the riprap submerged permeable breakwater. we study the wave absorbing characteristics, fragmentation patterns and wave height changes along the bed when the sinusoidal wave pass through the breakwaters, besides, we investigate the relative crest depth a/H, wavsteepness H/L effect the transmission coefficient and reflection coefficient of the submerged breakwater.
