| Abstract: | The flood sluice of Jinjiqiao hydroelectric station is a broken ogee weir of low overfall dam.Its weir height is 2.0 m.The hydraulic characteristics are low water head,large discharge per unit width,small water head of upstream and downstream,low Fr of cushion pool water and big variation amplitude of tailwater.Through design of cushion pool of this station and hydraulic model experiment,we determined reasonably the structure dimension of cushion pool and reached the object which satisfied the baffle and erosion control and save the investment. |
