This paper illustrates the role of analytical solutions in evaluating the settlements caused by tunnel excavation in soft soils. Analytical solutions have been obtained for shallow tunnels in isotropic and cross-anisotropic linear soil half-plane. These solutions provide a frame of reference for establishing numerical accuracy in FE analyses and for understanding the role of actual non-linear, inelastic soil behavior on far-field ground movements.
