Research conclusions: From the analysis of loading bearing of the different lining rigidities of the shield tunnel，it is concluded that only increasing the rigidity of the segment alone can not improve the seismic performance of shield tunnel，but increases the load on the segment． With the increase of the rigidity of the tunnel lining，the displacement of the lining structure is reduced by less than 2 mm，thus it is not obvious to restrain the deformation of the shield tunnel by increasing the lining rigidity under the effect of earthquake．
