Mathematical Model of Flood Discharge Atomization of High Rockfill Dam
In this paper,the mathematical model of random splashing was used to predict the impact of flood discharge atomization under three typical flood discharge conditions of a power station in the Yellow River,and also the two conditions of no natural wind and the most unfavorable natural wind throughout the year were considered.The contour map of rainfall intensity distribution was obtained,which could provide a reference for guiding the design of downstream slope protection.According to the calculation,the flood discharge atomization rainstorm area was 154～653 m along the river channel from the outlet section of the surface hole spillway,below the elevation of 2 880 m on the left bank and elevation of 2 828 m on the right bank.In this area,shallow anchor shotcrete could be used to proted the slope,and set horse path and drainage ditch to improve the safety and stability of the bank slope.Also the local natural wind speed was large,which had a significant impact on the atomization range.Additional attention needed to be paid to slope protection on the left bank.
