摘要
高拱坝大流量坝身泄洪几乎全部采用挑流消能方式,为此分析了国内外关于挑射水流对岩石河床冲刷的各种理论,并对高拱坝挑流消能冲坑深度预测、基岩冲刷的模拟方法、岩石冲刷破坏机理研究等问题进行了综述。同时提出岩石河床冲刷研究的关键课题。
The free jet energy dissipation is adopted on nearly all kinds of high arch dams. Various theories for the free jet scour on rocky riverbed at home and abroad are analyzed herein, and then the prediction of the depth of the scouring pit from the free jet energy dissipation, the methods for the simulation of the bedrock scour ,and the destroying mechanism of the scour on rock, ect. are summarized. At the same time, a key study subject on the rock riverbed scour is put forward as well.
