摘　　要：泄洪雾化现象是伴随着高坝泄洪消能带来的一个负面效应,它对于电厂的安全运行、周围环境等有一定的影响。采用大比尺模型试验方法研究向家坝水电站泄洪雾化问题,利用类似消能工的湾塘水电站泄洪雾化原型观测成果,反馈分析了雾化模型尺度效应,得到了雾化量的相似律,并预测和评价了向家坝水电站泄洪雾化影响。The phenomenon of discharge atomization occurs as hydraulic structures discharging, affecting the safety of power stations, electrical equipment and producing environmental pollution. In this study, the means of large scale model is used to study the discharge atomization problem for Xiangjiaba power station. The feedback analysis is carried out for the model law of atomization using the field measured data of Wantang power station similar to that of Xiangjiaba power station on the side of energy dissipation. Atomization intensities and zones of Xiangjiaba power station is forecasted.
