摘要
为评价某调蓄水库工程水工建筑物规划设计的合理性,从改善进口流态消除进气漩涡的角度出发,采用水工模型试验方法,分析了工程底孔进水口漩涡形成的原因,进而提出了布设消涡梁和加高上游挡墙高程两种消涡措施,并通过模型试验比较验证,从结构简单、便于管理、经济实用方面考虑,推荐加高上游挡墙高程到临界淹没水位620 m为底孔消涡措施。
The method of hydraulic model test was used to evaluate the rationality of hydraulic structure planning and design of a certain regulating reservoir from the aspects of improving inlet flow regime and removing air vortex. And then the cause of inlet vortex of bottom hole was analyzed. Two vortex suppression measures were proposed. One of the measures was setting vortex suppression beams,and the other one was heightening the upstream retaining wall. By comparing the model tests,based on the aspects of simple structure,convenient for management,economic and practical,the recommended measure is approved that heightening the upstream retaining wall elevation to the critical submerged water level 620 m could get the better effect of vortex suppression of bottom outlets.
