摘　　要：高坝泄洪形成的雾化现象对枢纽下游建筑物运行、两侧岸坡稳定及生态环境可能造成危害,严重时可危及枢纽本身安全。伴随着系列原型观测、数学模型及物理模型试验等形成的雾雨强度预测技术的发展,泄洪雾化工程防护由被动的雾化—破坏—修复逐渐演变为在预测雨强及其范围基础上进行工程防护,并逐步与消能建筑物、高边坡的分区、分段防护相结合。通过对系列工程雾化防护措施调研,对高坝泄洪雾化工程防护相关研究成果进行归纳总结,认为不同防护材料在不同雨强的破坏特性及雾化对生态环境的影响是今后泄洪雾化工程防护措施研究的重要方向。When flood is released from high dam, water flow atomization may cause damage to the downstream buildings, the bank slope of both sides and the ecological environment, and even will threaten the safety of the pro- ject itself. Due to the continuous development of fog-rain intensity forecasting technique which is driven by proto- type investigation, mathematical model research and physical model experiment, the engineering protection against flood discharge atomization has evolved from passive damage-restoration to actively adopting protection measures ac- cording to the prediction of rainfall intensity and atomization zone, and further developed to sectionalized protection of energy dissipating buildings and high side slopes. In this article, we summarize the investigation data of engi- neering protection measures and related research results, and conclude that the damage behavior of various protec- tion materials in the presence of different rainfall intensities and the impact of atomization on coo-environment are important research tendencies in this regard .
