摘要
Abstract
In the hydraulic model test of the spillway of Shajing Reservoir,the comparison of the hydraulic characteristics between the conventional continuous flip bucket and the slit-type flip bucket is made.The results show that in the discharge condition of flood frequency P=3.33%～1%,the depth of scour hole in the downstream riverbed of slit-type flip bucket is about 67%～73%of the corresponding depth of the continuous flip bucket scour,the effect of slit-type bucket is more obvious on reducing the scour depth,and the hydrodynamic load on the two side walls of the slit-type bucket is much greater than that of the continuous bucket walls,which should be taken seriously in engineering design.The results can be used as reference for similar engineering design and operation.关键词
