The invention relates to the technical field of aircraft load bridges, in particular to an aircraft-bridge coupling model construction method and system and a model analysis method, which can obtain aircraft design parameters and construct an aircraft model according to the aircraft design parameters. Acquiring aircraft load bridge design parameters, and constructing a bridge flexible body model according to the aircraft load bridge design parameters; and according to the interaction relationship between the airplane model and the bridge flexible body model, constructing an airplane-bridge coupling model. It can be understood that the model constructed according to the technical scheme can accurately simulate the sliding and landing process of an airplane on a bridge, connection and coupling solving of an airplane model and a bridge model are achieved, and then the influence of different sliding and landing states of the airplane on bridge dynamic response and the change rule of the influence can be analyzed
