Experimental research of turbulence kinetic and water force acting on spur dike

The waterlogging phenomenon of spur dike as a common type of waterway regulation building is very common. In this article, turbulence and mechanics research around the spur dike was carried out through physical model experiment; which illuminates the turbulence and Karman Vortex of spur dike erosion, the influence of pulsation kinetic energy is established and the corresponding relationship between pulse pressure and local scour, analyzed the Karman Vortex and the relationship between the dike after flushing, the influence of different influencing factors (discharge, water depth, bottom slope, length of spur dike) on the force of spur dike is systematically analyzed. The research results are of great significance for understanding the mechanism of scour and failure of spur dikes, and can provide reference for the design of spur dikes.
