Design model for shield lining segments and distribution of load

Zhu Hehua Cui Maoyu Yang Jinsong (Department of Geotechnical Engineering, Tongji University, Shanghai,200092)  
A new design model for shield lining segments, beam-discontinuous joint model, is described in this paper. And based on the new model, the distribution mode and value of the loading pressure on the lining segments are back analyzed using the measured data of segment pieces such as axial force and bending moment etc. In addition, a partial-peripheral ground spring model is compared with a whole peripheral one in the backward analysis.
