Abstract

A new model of joints between lining circle is proposed according to the characteristic of stagger-jointed assembling shield tunnel. The method of ascertaining the parameters and the range of the parameters are given in this paper. Using this model, a qusi-3D simulation model is obtain to analysis the internal force of segmental linings in stagger-jointed assembling. The operation stage of a water diversion tunnel in Shanghai is analyzed, which indicates that the stagger-jointed assembling structure´s relative displacement is less than straight-joint assembling structure and its internal force is larger than straight-joint assembling structure. It shows that the bilinear shear model is effective to reflect the constraint effect of stagger-jointed segmental linings of shield tunnel.
