本文阐述了潮汐通道边坡潮流、悬沙垂向结构，并建立了边坡流速垂向梯度解析式．通过理论关系式和现场观测资料分析论证，得知横向湍流掺混作用是造成边坡流速垂向分布较均匀的主要动力机理．考虑到潮汐通道边坡水动力场和悬沙场分布特点，应用平面二维泥沙运动数值模式模拟边坡区底床冲淤趋势．模式经岙山边坡试算，所获结果与该底床冲淤现状基本一致
In this paper, the trend of tidal channel slope and vertical structure of suspended sediment are expounded, and the vertical gradient analytical formula of slope velocity is established. Through the analysis and demonstration of theoretical relationship and on-site observation data, it is learned that the lateral turbulence mixing is the main dynamic mechanism that causes the vertical distribution of slope velocity. Taking into account the distribution characteristics of hydrodynamic and suspended sediment in the tidal channel slope, the numerical simulation of two-dimensional sediment movement is used to simulate the sedimentation and deposition of the bottom of the slope. The model was calculated by the slope of the hillside and the results obtained are basically the same as the current status of the sedimentation of the bed
