| 摘 要： | 主要介绍了特征线法在溪洛渡泄洪洞挑流鼻坎设计中的应用情况，采用特征线法建立了异形扭曲底面条件下的泄洪洞挑坎水流流场计算数学模型并编制了可视化计算程序，由计算结果可以得到挑坎上水流的自由表面形态、断面水深和沿垂线平均的流速分布，该模型计算结果得到了物理模型试验的验证，二者结果基本一致，从布表明该计算模型的可靠性，采用该计算模型能够直观、快速地进行挑坎体型的方案比较。

| Abstract: | Application and research of method of characteristics in design of flip bucket for spillway tunnel at Xiluodu Hydropower Project is mainly presented . Flow field in flip bucket flow in spillway is established under heterogeneous and tortuous bottom by method of characteristics . Mathematical model is calculated and visualized calculation program is composed . Flow pattern of free water surface , section water depth and average flow velocity distribution for plumb line in flip bucket flow are obtained from computation results which are verified by physical model test . The results of two models are consisted each other , proving reliability of the model . Alternatives for flip bucket shape can be compared intuitively and rapidly with the model . |
