| 摘 要： | 结合浙江苍南电厂工程要求,在拟建航道处的试挖槽附近取样,对粘性淤泥的起动进行了室内水槽试验。起动试验资料表明,在底床泥沙湿容重相同时,波流共同作用下或纯波浪作用下淤泥的起动流速明显小于纯水流作用下淤泥的起动流速,且起动流速随底床泥沙湿容重的增大而增大。

| Abstract: | A flume test is carried out on the threshold velocity for the coherent silt sampled in the sea area near the Cangnan power plant in Zhejiang Province.The test results indicated that the threshold velocity of coherent silt under both wave and flow action or single wave action is much less than that under single flow action for the same wet density silt,and increases with the increase of the wet density. |

| Keywords: | incipient motion of coherent silt wet density flume test |
