| 摘 要： | 提出了一种改进的砂质海岸岸滩演变的“一线理论”数学模型.该模型中考虑了岸滩演变过程中岸滩坡度变化的影响,并采用波浪折射、绕射和反射联合计算数学模型模拟掩护区的波浪场,提高了波浪计算的精度.实例计算表明,在验证资料比较充分的条件下,该数学模型计算结果的可靠度较高,可供实际工程规划和设计时参考使用.

| Abstract: | A reformed numerical model based on one line theory for beach deformation is presented. In this model, the change of slope of beach during beach procession is considered. A wave numerical model combined with wave refraction, diffraction and reflection is used to simulate wave climate to increase the numerical accuracy. The results show that the numerical model has a good precision based on enough field data. The results can be applied to real engineering. |
