Abstract: Based on the analysis of the connotation and typical characteristics of intelligent beam yards, this paper designed the overall architecture of intelligent beam yards for high-speed railways to address the problems of low production efficiency, poor process coordination, and high resource loss rate in traditional beam yards, introduced key technologies such as Building Information Modeling (BIM), digital twins, intelligent Internet of Things, and Artificial Intelligence (AI) assisted production. Taking the Xinbin beam yard of the Shenyang - Changbai Mountain high-speed railway as an example, it significantly improved the production efficiency and engineering quality of the beam yard and reduced costs by adopting intelligent and standardized processes such as steel bar processing and fine modeling, promoted the transformation of bridge prefabrication production towards digitalization and intelligence.
