错口丁坝在水流中的相互作用

Interaction between Alternate Groins in Water Flow

通过水槽实验和理论上的分析推导，得到了错口丁坝的主流流场和压强场变化规律，导出了丁坝错口布置状态下，上游坝的最小回流长度，从而揭示了错口丁坝间相互作用、相互影响的机理．为进一步探讨了坝群的回流尺度提供了一个基础性的方法和思路．

Based on theoretical and experiemtal investigation, the law of the velocity field and the pressure field of the main flow for the alternate groins is found. The minimum length of recirculating flow behind the upper groin is obtained. Meanwhile, the interaction between alternate groins in water flow is analyzed. Therefore, this article can be used as reference in the furthur study of the velocity field and recirculating flow region caused by the groin system.
