高坝泄流雾化环境污染原体观测研究

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。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,并配合以雨量简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。

Prototype Observation about Discharge Atomization Pollution at High Dam

Serious atomization occurs as hydraulic structures discharging high water head and large discharge,producing environmental pollution to hydraulic engineering and pepple's daily life and working conditions.It is an important problem which should be considered.Theories of measuremental methods used in prototype observation are presented in this paper.Radioisotope is applied to measure the atomization concentration in typical area.Stereophotogrammetry is applied to measure the shape and area of atomization flow.And atomization rainfall strength is measured by raing ages.The results provide scientific basis for the safe management of practical hydrauli cengineering and first hand data for the study of discharge atomization mechanism.
