| Abstract: | When the tailrace tunnel of Guangdong Pumped-storage Power Plant in the first phrase was filled by water,the off-stability deformations of the steel liner in the transition section have occurred in the four draft-tube branchesto different degree. This paper describes briefly the off-stability causes of the steel liner in the transition section of the draft-tube branches and their treatment measures, the steel liner repairment, reinforcement and welding, and the construction techniques of the TUL waterproof paint made in USA, which could provide the lessons for the design and construction of new projects. |
