This paper introduces the design method to reinforce the thin wall sluice pier by pasting the steel bar to the shallow groove.Through the crack detection and engineering mechanics calculation,a safety hazard was found in the thin wall pier of sluice gate in the Jinweizhou hydropower plant.The reinforcement scheme of shallow groove paste steel bar was proposed to solve the problem,and finite element simulation was performed for the optimal design of reinforcement scheme.No similar approach has been included ...
