CADMAS-SURF是一个有用的工具，以评估波浪作用的海岸结构。然而，有几个研究不规则波使用CADMAS-SURF。本文的目的是检查CADMASSURF的不规则波引起的越浪率的适用性。利用CADMAS-SURF软件计算了均匀底和倾斜底条件下的越浪率。将计算的越浪率与现有的越浪率公式进行了比较。计算结果表明，CADMAS-SURF能够在较宽的条件下估算不规则波的越浪率，其精度与现有公式相当。还可以确定波浪不规则性引起的短期越浪率。
CADMAS-SURF is a useful tool to evaluate wave actions for coastal structures. However, there are few studies concerning irregular waves by using CADMAS-SURF. The aim of this paper is to examine the applicability of CADMASSURF for the wave overtopping rate caused by irregular waves. The wave overtopping rate was calculated for uniform and sloped bottom conditions by using CADMAS-SURF. The calculated wave overtopping rate was compared with existing formulae. It is shown that CADMAS-SURF is capable of estimating the wave overtopping rate by irregular waves under broad condition with almost the same accuracy of existing formulae. It is also possible to determine the short-term overtopping rate caused by wave irregularity.
