The influence of some factors on the internal force of lining segment is analyzed, such as the section form, the thickness of the segment, the block number and the joint bending stifness.The results show that the sections of similar ellipse and the curved wall and arch are the best on bearing force under the condition of four section forms. Changing the number of the block affects small on the intermal force of the segment. The influence of bending moment and shearing force of the lining segment is greater than axial force with the change of joint stifness. The change of internal force is rapid when the joint stiffness is small, and then flattens.
