深水航道对波浪传播影响规律的研究

Influence Pattern of Deep Water Channels upon Wave Propagation

航道对波浪的作用已经成为深水港建设的关键技术 ,本文就航道对波浪传播的影响规律进行了广泛的探讨。根据物理模型和数学模型的试验结果 ,分别阐述了航道水深、航道边坡坡度、航道宽度、海底坡度以及波浪入射角对波浪传播变形的影响。文中还就临界入射角在工程中的意义、截短航道进行模型试验的可行性以及最大波高与水深比等进行了分析与论证。研究成果对港口及航道工程的规划设计具有指导意义。

The impact of navigation channels upon waves has become a key technique in the construction of deep water ports and harbours The pattern of influence of navigation channels upon wave propagation is extensively discussed in the paper The influence of water depth, slope gradient and width of a channel, gradient of sea bed, and incident angle of waves upon the propagation and deformation of waves is elaborated on the basis of the results of physical and mathematical model tests The significance of critical incident angle in engineering practice, feasibility of carrying out model tests with shortened channels, and ratio of maximum wave height to water depth are also analyzed and demoustrated The results of the research provide guidelines for the planning and designing of port and navigation channel works
