沙迳水库溢洪道窄缝式挑坎水力特性试验研究OA
Experimental Study on Hydraulic Characteristics of Slit-type Flip Bucket in the Spillway of Shajing Reservoir
在沙迳水库溢洪道水工模型试验中,进行了常规连续挑坎与窄缝挑坎水力特性的比较.试验表明,在洪水频率P=3.33%～1%流量泄流运行条件下,窄缝挑坎下游河床冲坑深度约为连续挑坎相应冲坑深度的67%～73%,窄缝挑坎减轻下游河床冲刷深度的效果较明显;窄缝挑坎两侧边墙承受的动水荷载比常规挑坎边墙大得多,应引起工程设计的重视.研究成果可供类似工程设计和运行参考.
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.
