Application of Segmental Prefabrication Method in Railway Bridge Construction

Abstract

Segmental prefabrication construction method is a bridge construction technology that divides a span bridge into several segments along the axis direction, prefabricated in batch at the beam yard and transported to the construction site for assembly. This method has been gradually popularized for its advantages of rapid construction, green environment protection and strong adaptability. In this paper, the application status of this method at home and abroad, the key points of construction technology are summarized, and the technical characteristics, advantages and disadvantages are summarized, so as to provide a reference for the project using this method.
