葛洲坝枢纽三江引航道冲沙时泥沙输移特性

Sediment-Transporting Charateristics on the Third Approach Channel at Gezhouba Project during Sluicing Sediment

本文根据原型实测资料、模型试验以及分析计算,对葛洲坝三江引航道冲沙期泥沙输移特性进行了研究,揭示了水流和泥沙的相互关系,并提出进一步改进的措施,以提高引航道的冲沙效率。

Based on the prototype observation data, model experiment and analysis calculation, this paper makes a study of sediment-transporting characteristics on the Third approach channel at Gezhouba Project during sluicing sediment. Relation of water flow to sediment transport is revealed. The improving measures are proposed so as to promot the sand- sluicing efficiency of the approach channel.
