摘　　要：水工建筑物进水口前形成的立轴吸气漩涡会造成对建筑物的破坏。文章以某水电站为依托,通过模型试验的方法对导流洞进口过流进行验证及研究比较,得出消除导流洞进口漩涡的体型优化方案。通过水力学模型试验优化导流洞进口结构体型,消除进口漩涡,对导流洞安全运行具有重要意义。Vertical inspired vortex formedat the intake of the hydraulic structure will destructthe buildings.Based on a hyd ropower station,this paper verifies and compares the inlet passage of diversion tunnel through model test,and obtains the optimal scheme to eliminate the inlet vortex of diversion tunnel.Hydraulic model test is used to optimize the intake structure,intake vortex vortex elimination measures are important for safe operation of diversion tunnel.
