摘　　要：利用水槽试验和理论分析相结合,在定床方面,讨论了丁坝挑角对壅水的影响;在动床方面,提出了补偿流量的概念,并结合定床壅水公式,给出动床淹没群坝壅水计算方法,计算结果与水槽实测资料相符。在此基础之上,进一步讨论了航道整治建筑物对河道行洪能力的影响。Based on the flume experiment and theoretical analysis,we discuss the impact of dike angle on backwater in the case of a rigid-bed,and propose the concept of compensation discharge for a live-bed.Combining the calculation formula of backwater height,we develop the calculation method for the backwater height associated with the submerged spur dikes on a live bed,the result by which fits well with the measured data.Furthermore,the influence of the waterway training structures on flood capacity of a river is also discussed.

关 键 词：阻挡流量 补偿流量 局部水头损失 壅水
