摘　　要：根据异重流运动的特点，从水体重率沿程变化的机理出发，推导出异重流计算公式 ，并用于大源渡船闸引航道淤积计算。通过类比分析，其淤积量分布与实测资料基本一致。Based on the characteristics of density current motion and proceeding the mechanism of variation of water body density on the way, the calculation for mula for density current was derived, which was applied for siltation calculatio n of Dayuandu Shiplock approach channel. Through analogical analysis, the siltat ion distribution calculated according to the formula was almost the same as the real－measured data.
