[0002] In the prior art, with the construction of various large and extra-large railway bridges, prefabricated bridge systems have been applied and developed. Among them, the prefabricated bridge system has the following characteristics during construction: good prefabrication quality, fast construction speed, no weather interference, mature conditions for transportation to the site for assembly, no impact on surrounding traffic during the day, and low carbon and environmental protection. In the existing prefabricated bridge system, the connection structure mostly uses grouting sleeves. On the one hand, it leads to a small connection range of the prefabricated segment, which is limited to the pier segment. It cannot be adaptively adjusted and calculated according to the relevant structures in the prefabricated bridge system. On the other hand, a large number of steel bars need to be set inside the pier, which has high assembly requirements. Therefore, there is an urgent need for an assembly calculation method for a prefabricated bridge system. By calculating the connection information of the outward-expanded segments at different positions, on the one hand, the connection range of the prefabricated segments is expanded, and on the other hand, the number of steel bars inside the pier is greatly reduced.
