摘要
姚家平水利枢纽工程洪水来流大、时间短,导致泄洪雾化影响极为严重.采用水滴随机喷溅数学模型和雾流扩散模型对姚家平水利枢纽泄洪雾化进行数值模拟研究,指出表孔单独泄洪时,雾雨强度大,主要影响两岸边坡,中孔参与泄洪后,将推动水雾向下游扩展,两岸坝坡雨强增大.最后依据数值模拟结果及现场地形地质条件制定相应雾化防护措施,有效节省雾化处理工程投资,可供类似工程雾化防护设计参考.
Abstract
The flood discharge induced atomization problem in Yaojiaping Water Conservancy Project is extremely seri-ous as the flood inflow is of large amount and short period.A numerical study is carried out on the atomization of flood discharge using the random droplets splashing mathematical model and the mist diffusion model.The results show that when the overflow dam spillways are operated alone,the intensity of the atomization mist and rainfall is high,and they will mainly affect the river banks on both sides.When the middle-level orifice spillways participate in the flood dis-charge,it will promote the downstream expansion of the atomization mist and rainfall and increase the rainfall intensity on the dam slopes.Then,targeted atomization protection measures are proposed based on the numerical simulation re-sults and the on-site topographical and geological conditions,which effectively save the investment in atomization treat-ment work.It can be useful reference for the atomization protection work design for similar projects.
