| Abstract: | The turbulent jet theory and water flow momentum equation are used to establish the mathematic model for calculating bedrock scoured balance depth of river bed under the action of left-right collision of water jet from high arch dam in considering 3-D diffusion,leakage collision flow and collision energy losses of water jet dispersion in the air.This model is tested to be rational and feasible via the experiments,being of reference significance for water cushion pool design and application under the action of water jet collision from high arch dam. |
