| 摘 要： | 本文通过水槽试验，对模拟冰盖流的河床泥沙起动流速进行了试验研究，探讨了冰盖流下河床泥沙起动流速的变化规律。试验表明:冰盖下泥沙起动流速与冰盖及槽底糙率的相对比值有关。

| Abstract: | Experiments were made for threshold velocity of the bed sediment as the channel was covered by ice. The experiment results show that the threshold velocity is affected by the ratio of roughness coefficient of ice cover and bed. |
| |
| Keywords: | ice cover roughness coefficient threshold velocity velocity distribution |
