FINITE ELEMENT ANALYSIS OF TUNNEL LININGS WITH EMPHASIS ON THE NONLINEARITY OF CONCRETE. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

The conventional analyses of tunnels where a linear elastic material is assumed for the concrete lining, is not satisfactory and sometimes contradictory. This is not surprising because the deformation of the soil causes restraints in the lining. In the present work a material model for reinforced concrete is developed which incorporates nonlinearity and cracking. With this model finite element analyses of a shallow cylindrical tunnel are performed. Some disadvantages of the conventional analyses are discussed and a modern safety concept based on Eurocode 2 is introduced. The results show that the ultimate load and the structural safety of the tunnel can be calculated satisfactorily. (Author/TRRL)
