摘要
本文根据饱和输沙和非饱和输沙的原理,分别导出了航道疏浚挖槽后淤积量的估算公式,并讨论了它们的适用范围;文中还根据实测水文泥沙资料,分析得到了伶仃洋海区潮汐水流的挟沙能力公式,可用于伶仃洋及其附近海区数学模型及泥沙计算.
Based on the principles of non-saturated transportation and settling of sediment in flow, the formulas of calculating siltation in dredged chan nels were derived in the paper. Because these formulas have strict theoretical basis, they are extensively practicable.In addition, according to the measured data of hydrology and sediment, the formula of the sediment transport capacity for the tidal flow in the Lingding Yang was obtained. It can be used to calculate sedimentation for the Lingding Yang and sea area nearby.
