Abstract: In order to better carry out the production of segmental beam in the short-line segmental precast yards, it is very necessary for the precast yards to estimate the production capacity before carrying out the prefabrication work. At present, there are few references about the engineering efficiency analysis and calculation of large-scale prefabrication task in China, and there is no detailed research. Therefore, the main factors affecting the segmental prefabrication production of large-scale precast yard are comprehensively considered, and it is very necessary to provide a method of efficiency analysis for large-scale precast yards. Furthermore, in view of the fact that the prefabrication plants are all existing precast yards with a certain production scale, a balanced model is established to simulate the capacity distribution of multiple precast yards, which can provide a reference for the early efficiency analysis of such projects in the future.
