摘要
基于泥沙运动的起动和止动条件分析了悬移质泥沙和床沙交换的内在机理,并根据这一机理推求了冲淤平衡状态下悬移质挟沙力级配的计算公式。经渭河实测资料验证,计算值与实测值基本相符,表明该计算公式具有良好的适用性,可在泥沙数学模型中参考应用。
Based on the starting and stopping conditions of sediment movement, this paper analyzes the intrinsic mechanism of exchange between the suspended load sediments and bed sediments. In terms of this mechanism, the calculation formula for the suspended load sediment-carrying capacity graduation under the balanced state of silting and scoring is deduced. The actuallymeasured data from the Weihe River test that the calculated values are found to be basically in agreement with the actually-measured values, whereby indicating that this calculation formula is of good applicability and can be used as the reference in the sediment math model.
