摘　　要：在“七五”、“八五”攻关的基础上，通过对小湾水电站泄流雾化的研究，进一步深化对高速泄流所产生的雾化水流的机理和防范措施的认识。其主要内容包括：（１）完善单一的较规则的挑流雾化水流计算模式，主要是完善雾流的横向扩散和考虑水弹性的溅水范围的计算方法；（２）水舌碰撞消能和窄缝消能的雾流量计算；（３）下游河床地形对雾化水流雨区的影响和两岸地形对雾流扩散的影响；（４）原型观测反馈计算；（５）小湾水电站泄洪雾化影响及防护范围。This paper presents a deep understanding of the mechanism of atomized water flow caused by high velocity water discharge and its preventive measures after deep - going study of atomization of water discharge for the Xiaowan hydropower project based on the achievements in tackling key problems included in the state scientific and technological research programs formulated during the state 7th and sib Five - Year Plan period. It mainly includes: (1) improvement of a simple and comparably regular trajectory atomized flow calculation model, focusing on the improvement of the calculation method of atomized now transverse divergence and water elasticity produced splashing extent; (2) calculation of collision energy dissipation and narrrow joint energy dissipation; (3) influence of downstream river bed topography on atomized now rain area and influence of both bank's topography on divergence of atomized water flow; (4) prototype observation feedback calculation; and (5) atomization influence and its prevention extent of water dicharge of the Xiaowan hydropower project.
