汉江游荡性河道航道整治计算方法研究

本文在理论分析和水槽试验的基础上,对丁坝回流长度、丁坝断面的垂线平均流速分布规律、整治线宽度和最大航深的计算方法等问题进行了研究,得到了相应的算式,同时还对汉江中游典型游荡性河段航道整治计算方法进行了探讨。

Study on the Estimating Method for the Braided Channel Regulation of Hanjiang River

Based on the theoretical analysis and laboratory investigation, the length of the back flow behind the groin, the distribution of the vertical average velocity along the groin's section, the width of the regulation line and the calculation mwthud for the maximun depth of navigation are studied, and the corresponding formulas are presented in this paper. The etimating methd is also discussed for the tyical braided channel regulation of the middle reach of Hanjiang River.
