[0002] Segment assembly is an important link in shield engineering, and its quality directly affects the stress condition of the tunnel and the safety of the overall project. During the assembly process, the standard block segment at the lower part is usually started, and then the standard segments on the left and right sides are alternately installed, followed by the assembly of adjacent block segments, and finally the top block segment is installed. During the assembly, attention should be paid to tightening the connecting bolts to ensure the firmness of the circumferential and axial connections. In the simulation of shield tunneling, the diameter of the ring corresponding to the segment used in the test is smaller, and the material quality is greatly reduced. Although the above conditions greatly facilitate the segment assembly work in the experiment, the existing test equipment does not have the functions of segment splicing and misaligned installation at the same time.
