【摘要】：针对车马碧水库竖式进水口处出现的立轴旋涡,利用水工模型试验,研究了进口水流流速以及淹没深度对该旋涡的影响,根据研究成果提出修建专门消涡建筑物消除旋涡的方案;结果表明:通过在竖式进水口周围设置12个消涡墩以及在进水口上方设置一消涡盖板组成消涡亭的方式实现在不影响泄流能力以及不过多增加工程量的基础上有效消除竖式进水口处的立轴旋涡的目的。研究成果可为竖式进水口消涡措施的布置提供参考。
[Abstract]:Aiming at the vertical vortex at the vertical inlet of Chemabi Reservoir, the influence of inlet flow velocity and submerged depth on the vortex is studied by hydraulic model test. According to the research results, the scheme of building a special vortex elimination building to eliminate vortex is put forward. The results show that by setting 12 vortex piers around the vertical inlet and a vortex suppression cover plate above the inlet, the vortex suppression pavilion can be realized without affecting the discharge capacity and not increasing the amount of engineering work. The purpose of eliminating vertical vortex at vertical intake. The results can provide a reference for the arrangement of the vortex elimination measures of the vertical intake.
