摘要: 各种型式的丁坝,在航道整治工程中,被广泛应用.其作用主要有束水、分流、挑流、护岸及改善航行水流条件.丁坝它能调节坝周泥沙的冲淤变化,刷深航槽,稳固河岸.本文通过对在非淹没条件下,正挑丁坝孔口断面的流速分布,及丁坝阻水流量的再分配进行了分析研究.该项试验研究成果在航道整治工程设计中,有较大意义和广泛的应用价值.

关键词: 丁坝, 束窄系数, 阻水流量, 阻水流量分配系数

Abstract: Spur dikes are ofton used in the hydraulis and waterway engineering. Based on a special model teston the velocity and obstructed-discharge distribution change in a non-submorged,orthogonal spur dike,the peper discusses the flow characters around the spue dike are alike to those in blending section. Theresult shows useful to elect an optimum waterway regulation line.

Key words: spur-dike, coefficient of contraction, obstrueted discharge, coefficient of obstructed discharge distribution
