The invention relates to the technical field of subway track laying engineering machinery, in particular to an automatic span changing method for a moving process of a running track between a shield section and a platform section. Compared with the prior art, the method has the following advantages: a trapezoid continuous span changing section track is pre-laid, The span changing operation in thetunnel does not need to use other auxiliary equipment for hoisting and supporting, so that the auxiliary cost investment is reduced; the use of an auxiliary transition track facilitates the rapid transition of a fast straight line running track to a section operation track and achieves the continuous operation of the track construction; zero time consumption of section span changing operation is achieved, the labor is greatly saved, and the construction speed is greatly improved; the laying of the section running track and the installation of the transaction track are both carried out underground, the construction uni
