A main frame structure having box-section bearing beams of a launch vehicle engine includes a body. The body includes upper bearing table tops, lower bearing table tops, a cross gasket, a connecting ring and the box-section bearing beams. The box-section bearing beam includes an upper surface, a lower surface and two side beam walls, and has a cavity structure. Penetrating transverse ribs penetrating the two side beam walls are arranged on the box-section bearing beams, and one ends of the box-section bearing beams are circumferentially distributed at an outer side of the connecting ring. The lower bearing table tops are arranged at the outer side of the connecting ring, the lower bearing table tops are connected to the cross gasket, and the other ends of the upper surfaces and the lower surfaces are connected by means of arc chamfers and are connected to the upper bearing table tops.
