An Efficient Post-Tensioned Prestressed Concrete Bridge Construction Approach

How to enhance the quality of concrete bridge is an important issue. Therefore, in this paper, we propose an efficient post-tensioned prestressed concrete bridge construction approach. At first, we explain the background theory of post-tensioned prestressed concrete bridge construction, and describe the process flow chart of the post-tensioned prestressed technology. Afterwards, we illustrate how to exploit the prestressed principle in concrete bridge construction. In addition, a hole is reserved below the eccentric distance in a concrete beam axis, and then high-strength steel can be installed and stretched. Then, normal stress of the concrete section is generated by the external load moment. In the end, we design an experiment to evaluate the performance of the proposed method via testing the vibration velocity under different truck speeds. Experimental results show that the post-tensioned prestressed technology can effectively enhance the safe level of the concrete bridge.
