摘要
根据岩基的抗冲能力,用原型岩基的允许流速换算成模型流速后作为起动流速的方法,来选择模型冲料粒径.提出选择模型冲料粒径时可用式V=8 D计算,并用工程实例进行了验证.
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.
