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