A sphere and cylinder combined annular pressure-resistant structure comprises a plurality of spherical shells. The spherical shells are connected in series to form an annular structure and are evenly distributed in the circumferential direction of the annular structure. Each spherical shell is provided with two circular orthogonal open holes which are located in the two sides of the connecting line between the center of the spherical shell and the circle center of the annular structure respectively. Every two adjacent spherical shells are connected through an annular rib cylindrical shell, wherein the two ends of the annular rib cylindrical shell are inserted into the circular orthogonal open holes in the two adjacent spherical shells respectively and fixedly connected with the two adjacent spherical shells. The spherical shells and the annular rib cylindrical shells are combined to form the special annular pressure-resistant structure, so that special advantages of the annular pressure-resistant structure are achieved; an existing mature spherical shell and cylindrical shell machining and forming technology can be utilized for manufacturing and forming the annular pressure-resistant structure, the problem that a typical annular pressure-resistant structure is difficult to machine and manufacture is solved, and the overall quality of the pressure-resistant structure is guaranteed.
