船闸引航道异重流淤积分析计算

根据异重流运动的特点,从水体重率沿程变化的机理出发,运用能量原理,推导出异重流淤积计算公式,并用于大源渡船闸引航道淤积计算。所得成果与已有3种公式计算结果的平均值相当,通过类比分析,所得淤积量分布与实测资料一致。

Analysis and Calculation of Sedimentation Caused by Density Current in the Approaching Channel

Based on the feature of density flow movement and varying mechanism of water body weight ratio along the channel, a formula for sedimentation caused by density flow was deduced by the principle of energy, which was used for calculating sedimentation of the approaching channel of Dayuandu Lock. The calculated result is corresponding to the average value of calculated results of the existing 3 formulas. And the distribution of sediment amount obtained from analogue is coincident with the measrred data.
