摘　　要：本文从分析竖井进流水平旋转内消能泄水道的流态及影响因素出发 ,根据试验资料对其泄量特性进行了系统地分析与研究。研究结果表明 :这种泄水道的流态、泄流量变化规律有非常明确的分区特性 ,不同的分区对流态与泄量的影响因素是不同的。本文在该分析的基础上给出了泄量的基本计算公式、流量系数的变化规律和泄量计算的经验公式。Base on experimental data, studies on discharge characterisitics of inner energy dissipating tunnel with inlet shaft and horizontal vortex, were systematically carried out. The flow pattern and relevant parameters were analyzed. The flow pattern and discharge characteristics of this type tunnel can be distinctly divided into different zones, where the influencing parameters on flow pattern and discharge were different. Some experimental formulas for calculating discharge and discharge coeflicient were derived.
