| 摘 要： | 为了探寻波浪破碎与波形不对称性的关系,通过对1/200缓坡上波浪破碎实验研究结果的进一步分析,运用最小二乘法,拟合了波形不对称性参数与相对水深的关系,以及用波形不对称性参数表示的波浪破碎指标表达式。所得规则波的结果与Kjeldsen的深水波结果相同,而不规则波的结果比规则波的小。研究还表明,这一破碎指标与相对水深有关系,随着水深变浅,指标值增大。 |

| Abstract: | In order to find the relationship between wave breaking and asymmetry of wave profiles,wave breaking indices described in asymmetric wave parameters are presented in this paper and formulas about asymmetric wave parameters and relative water depth are also proposed here by means of Least-Square Error Method,which is dependent on further analysis of wave breaking experiment carried out on 1/200 slope.The results of regular waves in the present study are the same as those got by Kjeldsen in deep water conditions,which are greater than those of irregular waves.The research shows that the indices determined in this paper depend on relative water depth: the shallower the water depth,the greater the indices. |
