| 摘 要： | 通过新疆喀什河吉林台一级水电站引水隧洞水力学模型试验，对深孔式无压隧洞洞内消能及消能工型式进行试验研究的成果，提出了在无压隧洞洞内设置消力池加悬栅的消能工型式。试验表明，悬栅的置入增大了掺气量，并且起到了破碎水跃表面波浪的作用，从而削弱了因池中水波而引发的下游洞内涌浪。该消能工的消能率达90％以上。

| Abstract: | The energy dissipation and the form of dissipater in deep hole free flow channel are studied in this paper through the hydraulic model experiment of diversion tunnel in Jilintai first-order hydropower station, which is located on Kashi river, Xinjiang. This paper reaches the new form of energy dissipater in free flow channel named suspended grid dissipater. The experiment indicates that aeration degree increased after putting suspended grid dissipater, and it also breaks the surface wave of hydraulic jump which can cause the surge in downstream. The computational results show that the damping ratio of such dissipater can be above 90%. |
