The invention discloses a safety margin calculation method of a wing reinforced wallboard. The safety margin calculation method of the wing reinforced wallboard comprises the following steps: step 1: acquiring parameters of a long truss unit and a skin covering the long truss unit, and relative position relation parameters between the long truss unit and the skin; step 2: acquiring relative position relation parameters between the wing reinforced wallboard and a wing box; step 3: calculating allowable compression stress of the long truss unit through a formula; step 4: calculating an allowable carrying capacity of the long truss unit, an actual working load of the long truss unit, a shearing allowable value of the wing reinforced wallboard and actual shearing stress on the wing reinforced wallboard in actual work through formulas; and step 5: calculating a safety margin of the wing reinforced wallboard through a formula. According to the safety margin calculation method of the wing reinforced wallboard, disclosed by the invention, the strength of the wing reinforced wallboard is metered in a manner of solving the safety margin of the wing reinforced wallboard; and the method is verified by a test, the structure efficiency can be improved and the design period is shortened.
