摘要: 排沙廊道是水电站设计中常见的一种建筑物,在工程设计中对于一些形态弯曲、结构及流态复杂的排沙廊道,目前能有效测算其泄流能力的计算公式并不多见。以南盘江大桥水电站为例,基于水电站首部枢纽水力学模型试验资料成果,以能量方程为基础,从单位流量所产生的阻力损失进行分析,建立了本工程复杂廊道泄流能力计算公式,计算成果同模型试验成果相吻合,可供类似工程设计参考,也为类似复杂建筑物泄流能力分析提供了研究思路。

Abstract: Flush gallery is a common structure of hydropower station. For flush galleries with bending shape and complex structure and flow pattern, the formula to effectively calculate the flow discharge capacity is seldom seen. Based on hydraulic model test data of the first part of Nanpanjiang Bridge Hydropower Station and the energy equation, we analyzed the loss of resistance per unit flow, and thus obtained the formula for the discharge capacity of the flush gallery. The calculation results conform well with physical model test results. This research  serves as a reference for similar projects, and provides a new idea to analyze the discharge capacity of such complex structures.             
