本文基于“解析松弛”的数值造波-消波技术,对单斜坡海堤越浪过程进行模拟,并将无风条件下单斜坡海堤越浪量与《堤防工程设计规范》中计算结果进行比较,两者误差接近30%。同时也对不同风速条件下单斜坡海堤越浪量进行比较统计,发现在风速小于20m/s的条件下,越浪量随着风速增加而增加;风速大于20m/s的条件下,越浪量随着风速增加而减小。 Based on the numerical wave-cancellation technique of “analytic relaxation ”, this paper simulates the wave course of single slope seawall and compares the over-wave of single slope sloping sea wall with the calculation result of “Code for Design of Dyke Engineering” The results are compared, the error between the two is close to 30%. At the same time, the statistics of over-waves of single-slope seawall under different wind speeds are also compared. It is found that the over-waves increase with the wind speed when the wind speed is less than 20m / s. The amount decreases as the wind speed increases.
