H.A.爱因斯坦-钱宁河工模型相似律及应用OA

River model is widely used in water conservancy engineerings.Although the research on model similarity law has been continuously improved and refined,there are still some divergences regarding specific scales such as sediment-carrying capacity of flow,particle settling velocity,and bed load movement similarity.Based on the principles of river dynamics and following the theories proposed by H.A.Einstein and Qian Ning,this study demonstrates the settling velocity scale that can ensure simultaneous similarity of sedimenta-tion and suspension,deduces the similarity scale of bed load movement according to the modified Einstein for-mula,and puts forward the restrictive conditions of the model distortion rate.The research verifies the reliabi-lity of the similarity scales and research methods proposed by previous scholars.Taking the model design of Chongqing Xiaonanhai Power Station as an example,the rationality of selecting various similarity scales was tested.
