Abstract: To improve the bending stiffness of steel plate structure, anchor bars and stiffeners are used to anchor the thin steel plate in the intake transition section in the concrete. In this paper, the finite element method is used to simulate the steel lining at the penstock intake transition section of hydropower station. The analysis results show that, the overall deformation of steel lining structure is small, which can meet the requirement of stiffness, the stress of steel lining structure is complex, the stress concentration at the stiffening ring is very high, the stress value of other parts is low, and the general stress value does not exceed 43.0 MPa, and the stress distribution is more uniform. The structural stress value of dam in the gate section is relatively low, through conventional reinforcement can meet the design requirements.

Keywords: penstock; steel lining; stiffening ring; intake transition section; finite element method; deformation analysis; simulation.
