Stress Analysis of Dam Pier Reinforced by Prestressed Self-locking Anchor
When an existing hydroelectric power station is used as the lower reservoir of a pumped-storage power station,the water level rises and the thrust of the gate increases,resulting in the bearing capacity of the existing gate piers fail to meet the requirements.In this paper,a scheme of installing super-large prestressed self-locking anchor bar is proposed.The finite element analysis method is used to analyze the prestressed self-locking anchoring scheme,and the analysis results show that the method could effectively reduce the maximum tensile stress of the piers.
