APPLICATION OF UPLIFT PILE WITH GENTLY BONDED PRESTRESSED
With the development of underground engineering in China,the application of unlift pile has been popularized.In order to solve the problems of cracking of traditional unlift pile and prestress loss of unbonded prestressed unlift pile,the gently bonded prestressed technology is applied.Combined with the practical project,the pile structure,technical parameters and construction technology of the gently bonded prestressed unlift pile are introduced.By comparing the original design of the project,the gently bonded prestressed unlift pile can greatly save the amount of reinforcement,the project cost and construction period.
