Abstract The bearing capacity，mechanical characteristics and damage mode of the special-shaped shield lining should be explored before application because of its special cross section. A 1∶1‘standing’prototype loading method for special-shaped segmental lining was suggested，and a‘standing’reconfigurable loading and data acquisition platform was developed with a hydraulic control system based on the closed-loop control theory of PLC. The internal force and deformation characteristics of the special-shaped shield lining structure under dead weight and overburden condition were analyzed respectively. The substantial influence of the structural self-weight on the internal force and deformation of the segmental lining under shallow overburden conditions was discovered. The limit burying depth of the lining structure was determined to be 18.5 m，and the analysis of the distribution of the cracks on the inner and outer surfaces of the segmental lining revealed the phenomenon of bending moment transfer.

Key words： tunneling engineering special-shaped shield prototype test 3D laser scanner crack bending moment transfer
