Application and effect of energy dissipation of T-shape pier of stilling pool

CHANG Yun-hua,etc.(Faculty of Prospecting & Surveying,ChangchunInstitution of Technology,Changchun 130012,China)  
By summarizing the research rusults of T-shaped pier stilling pools,along with prototype measurements,especially the fluid state in the stilling pool and the kind of construction well adapted to the tailwater,and compared to a flat bottomed stilling pool's length,depth and rate of energy dissipation,using prototype measurements.The result shows that the T-shaped pier stilling pool has a more compact structure,a higher rate of energy dissipation and hence a better effect on energy dissipation,along with a smaller wave in the tailwater and higher economic returns.It is an effective energy dissipation form and is well suited to middle or low water head dams.
