黄河口潮流波浪挟沙能力研究

Study on sediment Carrying Capacity of Tidal Waves

在前人研究的基础上,首先根据能量平衡原理得出了波浪挟沙力表达式,再将风暴和潮流对水流挟沙能力的影响一起计入水流挟沙能力,并考虑到河口水流所能挟带泥沙的含量是波浪、潮流、风暴同时叠加挟沙的结果,得出了潮波风暴水流挟沙能力计算公式。检验表明,计算值和实测值比较接近,可以用于实际工程中。

Based on the study of predecessors,it firstly obtains the formula of sediment carrying capacity of waves according to energy equilibrium principle,then calculate the sediment carrying capacity of flow including the influence of storm and tidal flow to the sediment carrying capacity of flow,considers the outcomes of additive sediment carrying of waves,tidal flow and storm because of sediment concentration at the estuary and obtains a formula for calculating the sediment carrying capacity of storm flow.It is shown by tests that it can be applied to practice for the values of calculation and observations are closer to each other.
