摘要/Abstract

摘要： 水沙关系研究是河道治理研究中的重要基础性内容。鲁台子水文站是淮河中游主要控制站,研究鲁台子水沙关系对于揭示淮河中游河床演变规律及河道治理有重要作用。基于张瑞瑾挟沙能力公式和曼宁公式,通过对淮河干流鲁台子至峡山口河段坡降流量关系及河相关系、河道糙率等的分析,推导出鲁台子输沙平衡、冲刷、淤积状态下的挟沙能力公式。采用1990—2007年实测输沙量对公式进行验证。经验证,建立的挟沙力概化公式基本反映了鲁台子站的水沙关系。

关键词: 水沙关系, 输沙平衡, 造床流量, 概化分析, 鲁台子水文站

Abstract: Study on the relationship between flow and sediment is an important content of basic research in the regulation of rivers. Lutaizi hydrological station is a major control station in the upper reaches of Huaihe River. Water-sediment relationship at this station is important in revealing the fluvial process and river regulation in middle Huaihe River. On the basis of Ruijin Zhang’s formula of sediment carrying capacity and the Manning equation, we derived the formula of sediment carrying capacity for Lutaizi station in different conditions (sediment equilibrium, erosion, deposition) by analysing the hydraulic gradient-flow relationship, hydrogeometric relationship, and channel roughness. Furthermore, we took the measured sediment load in 1990-2007 to verify this formula, and the result suggest that this formula could reflect the relation of flow and sediment of Lutaizi Station.

Key words: water-sediment relationship, equilibrium of sediment transport, channel forming discharge, generalizability analysis, Lutaizi hydrological station
