摘要

中文摘要: 采用概化模型试验探讨了新型水力翻板闸门的堰孔混合泄流能力，得到了开度、流量、水位的相关关系，提出了一种计算水力翻板闸堰孔混合泄流能力的新方法——修正系数法。试验成果表明，常用的综合流量系数法有较好的精度，其中，多项式拟合最优，线性拟合其次，指数拟合相对较低；修正系数法较常用的综合流量系数法具有更好的精度及实用性。该研究成果为新型水力翻板闸门的设计及应用可提供一定的参考价值。

Abstract

Abstract:Using a conceptual model test to explore new type of hydraulic flap gate mixed discharge capacity of weir and orifice flow

getting the relationship of opening degree

flow

and the water level

proposed a method of calculation the mixed discharge capacity of the hydraulic flap gate

which is the correction coefficient method. The test results indicated the common comprehensive discharge coefficient method has good accuracy

which polynomial fitting is the best

linear fitting is followed

and exponential fitting is relatively low; the formula of the correction coefficient has higher accuracy and better practical applicability compared to common comprehensive discharge coefficient method. The researching findings of the experiment provide a certain reference to the flap gate design and application.
