一种新型护面加翼块体的消浪特性试验研究
Experimental study on the wave dissipation characteristics of a new type of armor block
摘要
Abstract
In this paper,the wave dissipation performance of a new artificial armor block(so-called cross dolos)was evaluated by physical model experiment,and a number of indicators such as wave run-up,wave reflection coefficient,rough seepage coefficient and economic benefit were analyzed,and cross-comparison was made with accropodes.The results show that:the wave run-up increases with the increase of incident wave height,the wave run-up on accropode layers is greater than that on cross dolos layers,and the reflection coefficient of accropode layers is larger than that of cross dolos layers.A roughness coefficient of 0.383 is recommended for the reflected wave height formula of cross dolos as an average,while 0.456 is recommended for the wave climbing formula of cross dolos.Better wave dissipation performance is exhibited by the slope embankment with cross dolos,with the averaged wave reflectivity reduced by 18.5%and the averaged wave run-up reduced by 3.0%.Additionally,it demonstrates better economy with a cost reduction of 18.6%compared to equal-weight accropode.关键词
