| 摘 要： | 分析恒定清水冲刷水槽试验资料发现,推移质输沙率变化可分为两个阶段,即时均稳定阶段和衰减阶段。通过机理分析,建立了该两个阶段的计算公式,计算结果与试验资料吻合良好。该式可用来估算任一河段及任一时刻推移质输沙量及冲刷剖面。

| Abstract: | Based on the flume experiment data of steady clear water scouring,it's shown that the bed-load transport rate variation is divided into two phases,namely,time averaged steady phase and time averaged attenuation phase.According to the mechanism analysis calculation formula of the two phases are established and the calculated results are in good agreement with the tested.Therefore formula can be used to estimate the bed-load sediment transport capacity and scour profile at any reach and any time. |
