Abstract Based on the displacement formula of the tunnel wall，the shear stress on the interface of the fully grouted bolt is educed．Compared with the in-situ measurements，the different shear stress distributions are described for the distortion region，transition region，and stabilization region. The model of bolt shear stress in loose region is proposed；and the position of neutral point is obtained. Based on Mindlin¢s solution of displacement，the shear stress on the interface of the bolt behind neutral point is also derived considering the axial force of neutral point as concentrated force.
