Abstract

The role of analytical solutions in the evaluation of stress and displacement fields around tunnels is commented. The paper is divided into two parts. In the first part, ground loss and tunnel distortion are evaluated from elastic and elastic-plastic solutions, starting from the basic case of a circular tunnel at infinite depth and with uniform and isotropic initial stresses, and by introducing the effect of uneven stresses and finite depth. The second part deals with the analysis of distant deformations. Available solutions are used to derive surface and deep displacements. The results of observations in actual cases are used to assess the applicability of the solutions presented.
