摘　　要：雾化水流是泄水建筑物泄流时所形成的一种非自然的两相水流运动,其对水利水电工程的潜在威胁很大,雾化水流的溅水区则因其高降雨强度而成为对工程潜在危害最大的区域.对溅水区内雾化水流的降雨强度分布进行了试验研究,并探讨了对溅水区内降雨强度分布进行随机模拟的可能性.Atomized flow is an unnatural two-phase flow produced while water discharges at water release structures. This flow might threaten the normal operation of hydraulic and hydroelectric engineering owing to unnatural and high-density rain as well as unnatural and dirty mist; and the splash region is the region with highest rain intensity, thence much attention should be paid to during the design and operation of hydraulic and hydroelectric engineerings. In this paper rain intensity distribution in splash region of the atomized flow is investigated experimentally; and the method of random simulation is used to predict the rain intensity distribution in the splash region.
