The invention relates to the technical field of architectural engineering and aerospace, and aims to provide an unfoldable dome structure of a tension spring-driven shear hinge. The structure comprises at least three annular units, wherein rod members and node parts are connected in a hinged manner; low table parts of every two rod members are relatively assembled by screws to form shear hinge structures; six shear hinge structures are arranged in sequence, and are connected by twelve node parts to form one annular unit; the node parts at the external in one shear hinge structure are connected with the node parts at the same side at the internal through tension springs; the gathering state size of the structure depends on the section sizes and the length sizes of the rod members, and the spreading state size of the structure depends on the length sizes of the rod members, so that the gathering rate is higher, the small space requirement in rocket launching and the large space requirement in aerospace are satisfied, and the assembly, construction and transportation convenience requirements and the building space coverage requirement are satisfied; and the structure is convenient to be carried in the folding state, and is wide in functions in the spreading state. The structure is wide in application range, is gradient, and is higher in economic effect.
