The invention provides a large-wide-span-ratio aircraft load bridge load transverse distribution calculation method, and relates to the technical field of bridge structure design, and the method comprises the steps: obtaining basic structure parameters of a bridge, and solving the deformation quantity of each key control section under the action of unit load; according to the deformation quantity, the distribution counter-force of each main beam under the unit load effect is obtained, and the load transverse distribution influence line of each main beam is drawn; determining the load distribution range of the aircraft load according to the size of the main landing gear of the specific aircraft type, and adjusting the aircraft load in the load distribution range according to a preset step length to obtain a plurality of loading positions; and obtaining a load transverse distribution coefficient of each loading position according to the load transverse distribution influence line, and determining the load trans
