三亚电厂码头航道泥沙洄淤预测

本文从波浪掀沙和潮流输沙问题入手，对三亚电厂码头二种拟建方案的航道泥沙洄淤进行了预测。预测结果表明：航道的淤积强度呈自北向南递增的趋势，航道的南段淤积最重。在航道的北段，长山村方案淤积较重；在航道的南段，梅村方案的淤积较重。总体上看，二种方案均不属严重淤积。如果根据两种方案的洄淤分布特征对航道走向做适当调整，可望进一步改善航道的防淤效果。

Prediction of Siltation in the Approach Channel to Sanya Power Station

The prediction of the siltation problem in the approach channel to Sanya powerstation was made based on the wave and current.The calculated results shown that the suspendedsediment concentration in the whole area was low and higher value occured in the southern partof the channel.The calculation of siltation in the approach channel indicated that the siltationstrength will be gradually increased from north to south and the siltation problem in the harbourof the power station may not be serious.
