| Abstract: | The prestressed-reinforcement steel-pipe post scheme was implemented successfully in construction of Block No.0 of the Zhangjiagang Bridge under the Kunshan Municipality.Unbalanced moments which continuous box beams produced in cantilever construction were removed,giving rise to structure stability and safety.In combination with construction of the specific project,the thinking of designing the prestressed-reinforcement steel-pipe post scheme and calculation of the forces imposed on the support structure are elaborated. Issues for attention in using pointed-reinforcement steel-pipe posts are mentioned. |
