| 摘 要： | 在浙东开敞海区的淤泥质浅滩上开辟深水航道具有一定的风险。试挖槽试验表明,浅滩上泥沙粒径变化较大,台风作用下试挖槽内泥沙聚集,快速密实,淤积量较大,发生骤淤,仅存在少量的浮泥。骤淤现象主要由于浅滩处于破波带,泥沙属于极细沙,试挖槽内流动弱,槽底泥沙群体沉速大。 |

| Abstract: | The deep navigation channels constructed on the silt tidal flat in eastern Zhejiang Province may face the risk of typhoon sudden silt.The test in a trial excavated channel shows that the sudden silt during typhoons has been observed.The silt amount is quite large,the compaction is rapid,the sediment size varies in a large range,but little fluid mud can be found.The main reason to cause the typhoon sudden silt is that the sediment on the tidal flat,which is situated in broken wave zone,can be easily raised u... |
