Turbulent Kinetic Energy Distribution around Experimental Permeable Spur Dike
The spur dike is widely used in the waterway renovation project in the upper reaches of the Yangtze River as a remediation structure, but its water destruction is very common, and the influence of the permeable characteristics of the riprap spur dike on its stability has been neglected in many studies. Through the method of combining a generalized flume test and theoretical analysis, the influence of the submerged degree of the permeable spur dike, the porosity of the spur dike body, and the size of the void on its nearby turbulent kinetic energy is studied. The results show that the turbulent kinetic energy in the front of the spur dike increases with the increase of the submerged degree, decreases with the increase of the porosity, and first increases and then decreases with the increase of the pore size. At the axis of the dike, the turbulent kinetic energy increases with the increase of the submerged degree, decreases first and then increases with the increase of the porosity, and increases with the increase of the pore size. In the rear area of the dike, the turbulent kinetic energy decreases with the increase of the submerged degree, firstly decreases and then increases with the increase of the porosity, and first increases and then decreases with the increase of the pore size. The research results are of great significance to further understanding the water dike age of a permeable spur dike, and can provide scientific guidance for the design and restoration of spur dikes.
