| 摘要: |
| 通过室内水槽试验，描述了波浪作用下细颗粒泥沙的起动现象。在规则波作用下，天然沙和轻质模型沙的起动试验资料表明，天然沙的干重度随淤积历时的增长而增大，且起动时的波高和起动流速随泥沙干重度的增大而增加。电木粉的干重度对起动时的波高和起动流速影响很小。 |

| Abstract: |
| The threshold phenomenon of fine sediment under wave action is described based on a flume experiment. The data of the threshold experiment for natural sand and lightweight model sand under regular wave action show that the dry unit weight of natural sand increases with the extension of deposition duration; the threshold wave height and threshold velocity increase with the increase of the dry unit weight of natural sand; and the dry unit weight of the phenolic powder has little influence on the threshold wave height and threshold velocity. |
