Application of Elasto-Plastic Analysis to Tunnelling
Some applications are presented of the elasto-plastic and visco-plastic stress analysis to tunnelling problems. First, the closed form solution is recalled of the so-called “characteristic line” of a circular opening, which is frequently adopted for a sim

PREFACE
Numerical application ofplasticity to geomechanics is an area of research that has grown rapidly since its origins in the late 1960s. While early work was mainly confined to academic research, it is gratifying to see that the new growth area for some of these methodologies lies in geotechnical practice. There are at least two well-established conference circuits, one international association and various journals that emphasize numerical and analytical approaches to solving geomechanics problems. It is no coincidence though, that the evolution of numerical application ofplasticity to geomechanics, has run in parallel with the development of the finite element method and other numerical methods, and the extraordinary increase in power and speed of digital computers. This text contains papers that were presented as part of a course of the same name offered at the Centre International des Sciences et Mecaniques (CISM) in Udine, Italy in late June 2000. The material spans a remarkable range of topics, from theoretical developments involving novel algorithms and constitutive models to practical applications involving prediction of stresses and deformations in tunnel linings. The contributions are arranged in alphabetic order according to the first author, however if the reader wishes to move in an approximate route from theory to practice, he or she might start with the paper by Wo
