摘　　要：以某工程溢洪道挑流鼻坎为研究对象,采用物理模型试验的研究方法,以同等工况为试验研究前提,不同挑流鼻坎形态为研究方向。经试验得出不同鼻坎体型对应消力池下游水流流态、水流挑距、河床入射水流形态及河床冲刷形态。观测分析对比,得到适用于该工程实际的溢洪道鼻坎体型。The flip bucket of spillway of a project is taken as the study object,the physical model test as the study method,the equivalent operating conditions as the study preconditions,and the different flip bucket outlines as the study direction. The flow pattern,jumping distance,jet pattern and scouring corresponding to different flip bucket outlines in riverbed at downstream stilling basin are achieved through tests. From observation,comparison and analysis,the flip bucket outline actually suitable to the project is obtained.
