    The invention provides a method for checking total longitudinal shearing strength of a broadside large-opening ship. The method comprises the following steps: S1, establishing a main ship body finiteelement model in finite element software; S2, defining a loading condition of the finite element model of the main hull in NAPA software; S3, obtaining a draught value of the finite element model of the main hull and a shearing force Qx of an investigation section by utilizing the NAPA software; S4, applying gravity and buoyancy loads to the finite element model of the main hull, and setting boundary conditions; S5, setting an inspection point, and obtaining the shearing strength tau at the inspection point through calculation by means of the main hull finite element model; and S6, calculatingthe shearing strength tau' under the action of the designed shear force and comparing the shearing strength tau 'with an allowable stress tau 0. According to the method for checking the total longitudinal shearing strength of the broadside large-opening ship, the problem of checking the total longitudinal shearing strength of the broadside large-opening ship can be solved, meanwhile, huge workload is avoided, and the working efficiency and the accuracy of a checking result can be improved.
