| Abstract: | Based on the rock foundation erosion-resisting characteristics, the allowable flow velocity of the prototype rock foundation is converted into the modeling flow velocity that is used as the initial flow velocity for the model, with which the particle size of scouring materials for the modeling can be selected with the formula of V=8D. And then the method is demonstrated in the actual construction case as well. |
