| 摘 要： | 构皮滩工程泄洪流量和泄洪落差巨大，泄洪水舌入水激溅产生的强降雨及雾流对工程的安全以及电站的正常运行将产生一定的影响。通过物理模型试验研究和经验公式计算的方法，对构皮滩工程大坝泄洪雾化现象进行了较为深入的研究，分析了该工程泄洪雾化降雨强度分布特性，对降雨强度及雾流影响范围进行了预测。同时通过与相似工程类比，分析了构皮滩工程雾化降雨局部雨强大，雨强变化快以及两岸雨强分布不对称的特点。物理模型研究成果与经验公式计算和工程类比成果基本一致。

| Abstract: | The Goupitan Project is characterized by huge flood discharge and high fall, therefore, the strong rainfall and fog flow caused by flood discharge will have influence on the safety of the project and the normal operation of the plant. By the research on physical model and empiric formula calculation, a deepgoing research is conducted on the phenomena of local rainfall in the downstream of the dam caused by atomization of flood-discharge. On the basis of the study results, the characteristics of rainfall intensity are analysed and compared with those of the analogy projects. The measured data obtained in the physical model are basically accord with calculated results by an empiric formula. |
