摘要
以辽宁省高落差水闸——清河闸为例,水闸消能防冲设计应根据闸基地质、水力条件、闸门控制运用方式和工程投资等因素进行综合分析确定,比较了单级消力池、多级消力池、单级跌水不同方案消能工的设计、工程投资和消能效率等,讨论并推导了二级消力池消能计算的理论和方法。结果表明,优选单级跌水方案较经济合理。
The energy dissipation and erosion control design of sluice needs comprehensive analysis of geology condition of sluice foundation, hydraulic condition, gate operation and project investment. Taking high head gate in Liaoning Province for an example, energy dissipator design, project investment and efficiency of energy dissipation are compared for single stilling basin, multi-stilling basin, and single hydraulic drop. And then the calculation method of energy dissipation for two-stage stilling basin is discussed. The results show that the single hydraulic drop scheme is much more eco- nomic and reasonable.
