Analysis of the Stress and Deformation of the Prestressed Pier in a Hydropower Station Using Finite Element Method
The radial service gate of the surface overflow hole in a large hydropower station is under huge hydraulic thrust during normal water level.According to specifications and engineering experience,a prestressed reinforced concrete structure is adopted.A three-dimensional finite element model is established.The stress performance of the gate pier under three typical working conditions under prestressed is deeply explored.The results show that the gate pier structure owns considerable stiffness,the stress distribution conforms to general laws,and the layout of the prestressed system is reasonable.
