TUNNEL DESIGN USING THE TRAPDOOR PROBLEM. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

The 'trapdoor' problem has been used in conjunction with the finite element method to provide an understanding of the stress distribution around underground cavities. Using the principles of continuum mechanics, the ground reaction curves (grc) above the cavity roof have been computed assuming elasto-plastic soil behaviour. Parametric studies have provided a sufficient number of grc which were statistically processed to provide an equation, which could provide an indication of the long term stability of the unlined cavity.
