摘要
为使溢洪道具有较好的泄流条件,提高消能效率同时节省投资,提出了阶梯式溢洪道与掺气墩相结合的联合消能方式。以某水库溢洪道改造工程为例,对溢洪道的阶梯尺寸、掺气墩的结构及布置型式进行了探讨,最终泄槽段采用了1 m的阶梯形式与前倾30°的圆柱形掺气墩相结合的联合消能方式。试验结果表明,阶梯式消能工和掺气墩联合运用消能效果优异,水流条件明显改善。
The technology of stepped spillway combined with aeration piers are proposed to get better flow condition,sufficient energy dissipation and save the engineering investment. Based on the spillway reconstruction project of a reservoir,the spillway step size,aeration pier structure and layout were discussed and compared. The scheme of 1m stepped spillway and cylindrical aerated pier with forward leaning 30° was selected. The physical model test results show that joint application of stepped energy dissipator and aeration piers is excellent for energy dissipation and can improve the flow conditions as well.
