利用Rouse公式对长江口多次实测资料进行整理分析，得出了长江口北槽纵向悬沙垂线分布的特征，验证了描述悬浮泥沙垂线分布的Rouse公式的适用性，阐明了利用Rouse公式推算得到的不平衡条件下泥沙沉速与实际泥沙沉速的差异，并利用不平衡条件下的垂线分布公式和北槽悬沙垂线分布实测资料，率定和验证了不平衡输沙系数和垂线平均含沙量的经验关系式，在此基础上，建立了适用描述长江口北槽悬沙垂线分布的经验公式，并通过实测资料得到了验证。

Based on the Rouse formula, the suspended sediment characteristics of vertical distribution is studied and analyzed by data measured and collected in the Yangtze estuary, and the applicability of the formula Rouse is verified. The difference between the settling velocity of sediment calculated by Rouse formula and the actual sediment settling velocity is clarified. Using the sediment vertical distribution of measured data in the north channel, the relationship of the unbalanced empirical formula of sediment coefficient and vertical average sediment concentration is established, based on which, an empirical formula of vertical distribution of suspended sediment is established and verified by measured data.
