【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。
[Abstract]:In order to evaluate the rationality of the planning and design of a hydraulic structure in a reservoir regulation and storage project, from the point of view of improving the inlet flow pattern and eliminating the intake vortex, the causes of the formation of the swirl at the inlet of the bottom hole of the project are analyzed by using the hydraulic model test method. Furthermore, two kinds of vortex elimination measures are put forward, which are the arrangement of vortex elimination beam and the elevation of upstream retaining wall. Through the comparison of model test, it is considered from the aspects of simple structure, convenient management, economy and practice. It is recommended that raising the height of upstream retaining wall to critical inundation water level of 620m is a measure to eliminate vortex in bottom hole.
