Abstract

This article provides an overview of the current development status of prestressed segmental precast and assembled piers, Emphasis was placed on analyzing the stress characteristics of bridge piers under impact. The concept of recoverable functional design and its application prospects were elaborated, and finally, the research on the impact resistance performance of prestressed segmental precast and assembled piers was discussed. Research has shown that optimizing design and material selection can effectively enhance the impact resistance and structural durability of bridge piers. At the same time, the introduction of the concept of recoverable functionality provides new ideas for the rapid repair and functional recovery of bridge piers, which helps to improve the recovery efficiency of bridges after extreme events. Future research should focus on the evaluation methods of impact resistance performance, new connection technologies, in-depth application of recoverable functional design, a combination of impact simulation experiments and numerical analysis, and exploration of comprehensive disaster prevention and reduction strategies. These research results will also promote the further development and innovation of prefabricated assembly technology in bridge engineering, bringing new ideas and methods to the field of engineering construction.
