摘要
通过模型试验 ,研究了掺气分流墩台阶式溢洪道的水流流态和流速特性。结果表明 :此种消能工能改善台阶式溢洪道的水流流态 ,大幅度地减小水流流速。在试验范围内 ,掺气分流墩台阶式溢洪道的流速较相应光滑溢洪道减小了 1 8.4%～ 68.3 % ,较相应的台阶式溢洪道降低了 6.9%～ 54.0 %。
Water flow regime and flow velocity behaviors in stepped spillways with aerated piers are studied via the model tests.The results indicate that this kind of energy dissipation function can improve the water flow regime in the stepped spillways and reduce the flow velocity by a wide margin.Within the range of model tests,the flow velocity in the stepped spillways with aerated piers was reduced by 18.4%～68.3% in comparison with that in the corresponding smooth spillways,and by 6.9%～54.0% in contrast with that in the corresponding stepped spillways.
