Abstract

To effectively promote the quality of concrete bridge, in this paper, we propose a post-tensioned prestressed concrete bridge construction method. Firstly, we introduce the background theory of post-tensioned prestressed concrete bridge construction, and illustrate the process flow chart of the post-tensioned prestressed technology. Secondly, we discuss how to utilize the prestressed principle in concrete bridge construction. Particularly, a hole are reserved below the eccentric distance in a concrete beam axis, and then high-strength steel can be installed and stretched. Moreover, normal stress of the concrete section is produced by the external load moment. Finally, we conduct a simulation to make performance evaluation by testing the vibration velocity under various truck speeds. Simulation results demonstrate that the post-tensioned prestressed technology is able to promote the safe level of the concrete bridge.
