Assembly type subway station longitudinal bending mode recognition method, system, equipment and medium

The invention relates to the technical field of rail transit, and discloses an assembly type subway station longitudinal bending mode recognition method, system and device and a medium. The method comprises the following steps: obtaining a boundary value of a longitudinal bending mode according to an assembly type construction structure design parameter in advance; the first circular seam opening amount of the top plate block and the second circular seam opening amount of the bottom plate block are obtained through the two crack meters respectively; converting the first circular seam opening amount and the second circular seam opening amount into a first strain and a second strain respectively; according to the first strain, the second strain and the structural design parameters of the fabricated component, obtaining section bending moment and axial force at the centroid, and calculating the ratio of the section bending moment to the axial force at the centroid; and judging the longitudinal bending mode by co
