Abstract: Provided is a three-dimensional loading structure of an ultra-large physical simulation facility for deep engineering disasters. The three-dimensional loading structure comprises a horizontal ultra-large reaction frame, a vertical ultra-large reaction frame, ultra-long stroke lifting and locking hydraulic cylinders, five array distributed hydraulic actuator groups and a linear distributed hydraulic actuator group, wherein the horizontal ultra-large reaction frame adopts a frame structure being formed by splicing eight segments of arch beams, circular in an outer part and square in an inner part, and wrapped with prestressed carbon fibers, and the vertical ultra-large reaction frame adopts a double-beam four-column preload frame structure; the five array distributed hydraulic actuator groups are distributed around the horizontal ultra-large reaction frame and at a top of the vertical ultra-large reaction frame, and the linear distributed hydraulic actuator group is located at a center of a bottom of the vertical ultra-large reaction frame.
