摘要
提出波浪作用下岸坡和海底动态和静态平衡条件的数学模型。在已建立的推移质泥沙体积输沙率基本关系式的基础上,根据连续方程,计算出底坡、泥沙、波浪三要素在动态和静态平衡情况下的关系式,得出反映这种关系的底坡平衡函数曲线图。用实际资料对这一函数曲线进行了验证,并对实际资料相对模型的某些差异作出解释。
A mathematical model of equilibrium conditions of coastal slope and sea bottom under wave action is developed. According to the continuity equation based on. the equations of bedload sediment transport rates, the quantitalive relation among the slope, sediment and wave factors in case of dynamic and static equilibrium has been calculated, and represantated by a series of curves called the function curves of e-quilibrium bottom slopes. Testing the model by existing data shows that they are basically in agreement. The difference between the data and the model is explained.
