漫湾水电站泄流雾化原型观测研究

Prototype Observation and Study of Flood Discharge-caused Atomization at Manwan Hydropower Station

高水头大流量的泄水建筑物泄流时产生严重泄流雾化对工程和环境造成污染，是必须考虑的重要问题。文章介绍了泄流雾化观测的新技术及其原理，包括：用立体摄影测量方法观测雾化流运动扩散的形态范围；用放射性同位素测量典型区域内泄流雾化浓度，并配合以雨量筒测量典型范围内泄流雾化降雨强度等。并以漫湾水电站原体观测为实例，介绍了实施方法和效果。

The pollution caused by heavy atomization occurring during discharging flood at high flow rate under high waer head is an importan probem to be duly considetal. This paper presents the lateStmthdri of c0nduting atomization observation and their principles, including application of redioisotope to measure the atdrization concentration in a typical area, application of stereophotogrammetry to measure the shape and dispersion area of atomization flow and use of rain gauges to measure atdrization intensity. Taking the prototgpe observation at the Manwan Hydro -powr station as an example, the paper gives an introduction to its implementation methods and the results obtained.
