| 摘 要： | 本文在分析挖槽对流速影响的基础上,根据潮流和波浪的输沙机理,分别推求出潮流以及潮流和波浪联合作用下的淤泥质河床和沙质河床航道开挖后的回淤计算公式,经实测资料初步检验表明计算结果良好,可用于河口海湾地区航道的规划和设计。

An Estimate Method of Siltation for Dredged Channels in Estuaries |
| |
| Abstract: | Based on the machanism of sediment transport of waves and currents,and the analysis of the effect of dredging channel on the velocity, the formulas of calculating siltation under the coexistence of waves and currents are presented. It's shown from verification that the calculations are in good agreement with the measured data and can be widely used for the design of navigation in estuaries. |
