摘要
根据已有工程经验,初拟了阿海工程表孔X型宽尾墩+台阶面+消力池的泄洪建筑物消能布置形式,通过水力学模型试验研究发现,宽尾墩对泄流能力影响很小,泄流量不但满足设计要求,而且还有小幅度的超泄能力。宽尾墩水舌分流合理,也能适应不同泄洪流量与消能要求。堰面及消力池底板压强分布基本满足工程结构要求。下游河道冲淤变化量很小,个别工况无任何冲淤现象发生。
Based on the constructed project experience ,the paper preliminary designed layout type by the combination of X type flaring gate piers still basin on Ahai hydro power station.The result of model testing showed that this type of gate piers had very small impact on the spillway discharge,the actually discharge was more than design requirement.X type flaring gate piers water nappe distribution was feasible and could be suitable to different discharge energy dissipation.Pressure on crest still basin was in accordance with engineering structure.The sediment quantity of scour-silt was very small.
