中文摘要 |
In order to modify the spillway structure of a check dam and specify the geometry parameters of the spillway,the debris-flow pattern,scour depth,and energy dissipation were discussed under the conditions of different bottom surfaces and lateral contraction ratios based on physical modeling experiments. According to the buried depth design criteria for check-dam foundations and critical equilibrium for nonviscous particles under water,the rational value of the lateral contraction ratio was also discussed. The results indicated that the scour hole with deep scour depth was |
