Calculation and Analysis of Flood Discharge Atomization Range of Sluice Structure in a Project
In order to reduce the engineering influence and loss caused by flood discharge atomization,the author combines engineering examples and estimates the atomization range of surface hole spillway tunnel and flood discharge and sand flushing tunnel at different water levels based on theoretical formulas,and puts forward the corresponding engineering design suggestions according to the estimation results.The results show that the atomization influence range of the surface hole spillway tunnel is the largest under the check flood level;Although the plant area of the project is located outside the horizontal influence range of the heavy rainstorm area,it is within the range of the fog flow rainfall area,the adverse effects of atomization on the electrical equipment in the plant area should be considered in the design;The exit slope is partially located in the area of strong rainstorm and atomized flow rainfall area,it is necessary to reinforce the slope and take surface protection measures to ensure the safety and stability of the slope operation.The calculation results can provide theoretical support for engineering layout and design.
