The invention relates to a semispherical bearing structure at the bottom of a microgravity test cabin and a preparation method, the bearing structure comprises a large composite material bearing part, and the large composite material bearing part comprises a shell structure and a rib box type combined structure arranged on the bottom surface of the shell structure; the shell structure comprises a supporting leg structure and a conical surface shell arranged downwards from the middle of the shell structure, the rib box type combined structure is composed of a plurality of modularized rib box type units, and each rib box type unit is of an open box type structure; and the plurality of rib box-shaped units are annularly arranged at the bottom of the shell structure around the conical surface shell and are provided with outward openings, so that the whole formed rib box-shaped combined structure is arranged on the conical surface shell in a sleeving manner. The rib box type units are independently formed and then assembled into a rib box type combined structure, and the rib box type combined structure and the shell structure are co-cured and integrally formed.
