水平旋流泄洪洞水工模型试验分析

摘要

通过对竖井泄洪洞水工模型试验分析表明：当堰顶高程2500．5 m时，在校核、设计水位实测下泄流量均能满足设计要求，并有一定超泄余量；当起旋室、旋流洞直径分别为9．5和9．0 m时，各泄流条件下旋流洞均可形成典型的旋流流态，且空腔稳定。采用水平旋流洞与消能墩的组合，消能效果显著。%Through to the table shaft hole spillway tunnel hydraulic model test analysis:weir crest el-evation of 2500. 5 m, under the check, the design water level measured discharge can meet the de-sign requirements, and has a certain discharge allowance;Spin chamber, swirl hole diameter is 9. 5 m and 9. 0 m respectively, the discharge swirl hole can be formed under the condition of typical vor-tex flow, and the cavity stability;The level rotary flow tunnel and the combination of energy dissipa-tion piers, energy dissipation effect is remarkable.
