【摘要】：為評(píng)價(jià)某調(diào)蓄水庫(kù)工程水工建筑物規(guī)劃設(shè)計(jì)的合理性,從改善進(jìn)口流態(tài)消除進(jìn)氣漩渦的角度出發(fā),采用水工模型試驗(yàn)方法,分析了工程底孔進(jìn)水口漩渦形成的原因,進(jìn)而提出了布設(shè)消渦梁和加高上游擋墻高程兩種消渦措施,并通過模型試驗(yàn)比較驗(yàn)證,從結(jié)構(gòu)簡(jiǎn)單、便于管理、經(jīng)濟(jì)實(shí)用方面考慮,推薦加高上游擋墻高程到臨界淹沒水位620 m為底孔消渦措施。
[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.
