The invention relates to a parallel assembly double-arch out-of-plane instability experimental loading device. The device comprises jack base adjusting blocks, tension and compression jacks, stand columns, a bottom beam, a counter-force beam, sliding grooves, rolling shafts and rigid wedge blocks. The upper end face of the bottom beam is provided with a support used for placing a parallel assemblydouble-arch ring, and the jack base adjusting blocks are arranged on the counter-force beam; the jack base adjusting blocks are provided with the tension and compression jacks which are always parallel to the arc radial direction of the parallel assembly double-arch ring; the sliding grooves are formed in the lower portions of the jack base adjusting blocks, the rigid wedge blocks are arranged onthe upper portions of the tension and compression jacks, and the rolling shafts are arranged in the sliding grooves; the rigid wedge blocks are located below the rolling shafts, and the bottom facesof the sliding grooves are
