... bearing element is completely unaddressed in the Eurocode. On the other hand, the Guidelines for the geotechnical design of underground structures, published by the Austrian Society for Geomechanics represent a sound and practically tested design methodology. However, the issue of proofing that the chosen...

.... The estimate of these redistributed stresses in terms of magnitude and direction plays a vital role in design of the excavation. Alleviating the stress con- centration is of utmost importance to ensure safety of existing underground structures such as main drive, crosscut, and decline and also to maintain...
