An analytical solution for a jointed shield-driven tunnel lining

This paper presents an analytical solution for the prediction of internal forces and displacements of a jointed segmental precast circular tunnel lining. The effects of joint stiffness on the performance of the tunnel lining are discussed. The 'force method' is used to determine the internal forces and displacements of jointed tunnel lining. Five shield-driven tunnel cases are adopted to study the effects of joint stiffness, soil resistance, joint distribution and joint number on the internal forces and displacements of circular tunnels. Laboratory model tests are conducted to verify the proposed analytical solution. Copyright (C) 2001 John Wiley & Sons, Ltd.
