摘要
为研究多孔闸调度对消能效果的影响,采用物理模型试验的方法,观测了辽河双台子多孔闸不同闸门调度方式下的流态、流速和消力池尾部水流扩散宽度,分析了不同闸门调度方式下多孔闸的流态情况,并计算出不同方案下的消能率,确定了满足消能要求的两种闸门运行方案。根据分析结果,提出用池尾扩散比量化多孔闸的调度方法,简化了消能率的影响因子,得到了池尾扩散比和消能率的指数相关关系,可为类似工程提供参考。
On the basis of the model experiment of Shuangtaizi multi-outlet sluice located in Liaohe River,the flow patterns,flow velocity and flow diffusion widths at the end of stilling basin under different operation conditions are observed and measured to research the impact of the gate operation on energy dissipation.The flow patterns of multi-outlet sluice under different operation schemes are analyzed and the energy dissipation ratios are calculated under different schemes.The two operation schemes of the gate meeting the requirement of energy dissipation are determined.According to the results,the method of quantifying the multi-outlet sluice operations by using diffusion ratio at the end of stilling basin is proposed,the influencing factors of energy dissipation are simplified,and the exponential function between diffusion ratio at the end of the stilling basin and energy dissipation ratio is obtained,which can be a reference for the similar projects.
