摘要
本文建立了适用于弯曲程度不同时的河道泥沙起动流速公式，对环流非充分发展的、床面达到动平衡状态的弯曲河道推移质强烈输沙带进行了研究．导出了弯曲河道内强烈输沙带的曲线方程，经模型连续弯道内实测输沙带的位置和计算强烈输沙带曲线的比较，结果令人满意．
In this paper,the formulas of incipient velocity of sediment in different sinuous channels are given.The intense belts of bedload transport in sinuous channels for unfully developed currents and dynamic equilibrium bed belt are investigated.The curve equation of the intense belt of sediment transport in sinuous channel is deduced,which is satisfactorily coincided with the experimental data.
