Research on Hydraulic Characteristics of Swirling Flood Discharge Tunnel of Vertical Shaft

为了探究竖井旋流泄洪洞的水力特性,以山东某水利工程的竖井旋流泄洪洞为研究对象,通过压强测点获取泄洪洞的压强数据,并提出基于数值模拟的水力分析数值。结果显示,研究使用的数据获取方法可以有效完成泄洪洞的压强数据收集,且研究所得的水力分析结果与试验值之间误差保持在3%以内。表明研究方法能有效进行数据旋流泄洪洞的水力特性分析,对工程设计具有一定的指导意义。

In order to explore the hydraulic characteristics of the shaft swirling spillway tunnel,the pressure data in the shaft swirling spillway tunnel of a water conservancy project in Shandong province were obtained through pressure measuring points,and the hydraulic analysis value based on numerical simulation was put forward.The results show that the data acquisition method used in the study can effectively collect the pressure data of the spillway tunnel,and the error between the hydraulic analysis results and the test values is kept within 3%.The above results show that the research method can effectively analyze the hydraulic characteristics of the data swirling spillway tunnel,which has certain guiding value for engineering design.
