Smooth blasting technology for flood discharge tunnel of Xiluodu Hydropower Station on right bank

The aerators are widely used in flood discharge tunnels and spillways to prevent the cavitation damage of the structures,and air is sucked by flow from the bottom in normal aerator.

At first,the theory and the happening conditions of cavitation damage are presented,at the same time,the reasons of cavitation damage and the position where the cavitation damage usually takes place are analyzed in tunnel spillways.

The 4 tunnel spillways of Xiluodu Hydropower Project are located at both sides of the river valley.

Twenty two practical engineering examples of existing tunnel spillways collocted from at home and abroad are introduced in this paper.
