摘要
针对目前计算海床临界冲刷切应力公式适用性不强的问题,文章从实测资料出发,借助于波流共同作用下的泥沙数学模型,提出了一种经过验证的计算海床临界冲刷切应力的通用性方法。该方法不需要大范围的海域泥沙实测资料,其适用性相对较强,且能在一定程度上很好的保证海床临界冲刷切应力的连续性,减少人为随意的手动调试。
For the present problem that the applicability of the formula of calculating the seabed critical shear stress for erosion is not strong, starting from the measured data, a proven general method of calculating the seabed critical shear stress for erosion with the help of the sediment mathematical model under wave and tidal flow was put forward in this paper. This method does not need a wide range of the observed data of marine sediment, and its appli-cability is relatively strong. And to some extent, this method can guarantee the continuity of the seabed critical shear stress for erosion very well and reduce artificial optional manual debugging.
