海河口闸下泄流拖淤分析

海河口属淤泥质河口，其档潮闸下引河淤积问题极为严重，挖泥清淤虽然有效，但费用之高愈来愈连以承受，利用闸上有限泄流或闸下落潮流拖淤，寻找一种简捷，经济的清淤措施已引起海河流域水管部门的极大兴趣，本文对１９９４年海河干流挡潮闸下拖淤情况进行了全面的介绍和分析。

An analysis on sediment sluicing with agitation in downstream reach of barrage on Haihe Estuary

The Haihe Estuary is an estuary with mud and silt. The siltation in downstream reach of the tidal barage is severe. Dredging is an effective method.but the cost is more expensive. In orler to develop a convenivnt and economical measure,sediment scouring has been carried out by using a limited flow discharge released through the barrage or sluicing with agitation during ebb peri-od. An overall introduction and a brief analyisis on the sluicing with agitation in downstream of the barrage on the Haihe Estuary in 1994 are given in this paper.
