错口丁坝回流尺度的研究

Study on Recirculating Flow Range Caused by Groins Lying Alternately

通过理论分析和水槽实验，阐述了错口丁坝间相互影响的机理，得到了错口丁坝的回流长度、回流与主流的分界边线及其最大宽度公式。

y using the theoretical and experimental investigation,the principle of interaction between alternate groins in the river is found. The length, the boundary line and the width of recirculating flow caused by alternate groins are presented. Therefore,the paper may provide a reference for the further studing of the recirculating flow range caused by groin system.
