Influence Analysis of Spur Dikes on Bend Flow Characteristics
Spur Dike has the role of adjusting river flow potential,and is a common hydraulic structure.In this paper,the influence of the location of spur dikes on the flow characteristics in the bend is analyzed through experiments.The results show that the closer the layout of the groin is to the entrance of the bend,the lower the water flow velocity in front of the dam,and the higher the water flow velocity at the head of the dam;When the short spur dike is set at the 45 ° and 90 ° positions of the bend,the flow velocity on the left bank shows a trend of first decreasing and then increasing,while the flow velocity on the right bank shows a trend of first increasing and then decreasing.The above research can provide reference for spur dike construction.
