摘　　要：利用物理模型试验评估了一种新型人工护面块体(加翼块体)的消浪性能,分析了波浪爬高、波浪反射系数、糙渗系数和经济效益等多项指标,并与扭王字块体进行了横向对比。研究结果表明:波浪爬高随入射波高的增大而增大,波浪在加翼块体护面上的爬高要小于扭王字块体工况,加翼块体护面的斜坡堤反射系数整体上小于扭王字块体护面的斜坡堤;利用反射波高公式计算得到的加翼块体平均糙渗系数推荐值为0.383,利用波浪爬高公式计算得到加翼块体平均糙渗系数推荐值为0.456;加翼块体护面的斜坡堤与规则安装了同等重量扭王字块体的斜坡堤相比,具有更优的消浪性能(波浪反射率平均减小了18.5%、波浪爬高平均减小3.0%)和更好的经济性(造价减小18.6%)。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.
