Stress Distribution Around a Tunnel with an Arbitrary Cross Section Excavated in Anisotropic Elastic Ground

Abstract

The present paper is concerned with the theoretical determination of stresses and deformations around a tunnel with an arbitrary cross section excavated in anisotropic elastic ground under a three-dimensional stress state. In the first part general methods are proposed for determining these phenomena based on the use of comformal mappings, and in the second are given the numerical results of computation of some typical cross sections.
