摘要/Abstract

摘要： 高坝工程泄洪雾化引发的强降雨及雾流对水利工程和周围环境均产生较大影响。以往研究主要针对下游岸坡泄洪雾化雨强开展工作，少见对雾化源区域的研究。通过概化模型试验，在不同水力条件下对挑流水舌落入下游水体产生的雾化源区域的降雨强度进行系统测量和分析，针对泄洪雾化雾源区雨强的平面分布特征进行了研究，确定了落水点周围不同区域雾化源的形成原因和降雨强度平面分布规律，并对水舌落水区的区域范围和雨强分布特征随流量和水头差的变化情况进行了探索。

关键词: 泄洪雾化, 雾化源区, 水舌落水区, 降雨强度

Abstract: The heavy rainfall and mist flow induced by flood discharge atomization of high dam projects have negative effect on the hydropower project and its surrounding environment. Previous researches were focused on the rainfall intensity distribution on the downstream banks, while the source area of the atomization is still not well revealed. Through generalized hydraulic model tests, the rainfall intensity in the atomization source in the progress of a deflecting flow nappe dropping in the downstream water were measured, under different hydraulic conditions. The horizontal distribution was analyzed, and the causes of atomization sources and rainfall intensity distribution in the upstream, downstream and side regions around the nappe drop point were determined. The variation of nappe drop position and rainfall intensity distribution along with the change of water flow and head difference were also preliminarily investigated.

Key words: flood discharge atomization, atomization source area, nappe drop area, rainfall intensity
