Abstract
Uncertainty and variability is part of geotechnical design and need to be taken into account in the design process. This paper presents some of the work in progress of the sub-project of the Australian Centre for Geomechanics’ Ground Support Optimisation Project, specifically aiming at advancing risk based support design in mining application. The paper presents some thoughts on a general multi-tiered approach to support design but focuses on its application on only one aspect of the support design process, namely the evaluation of the depth of rock mass yielding. The use of elastic superposition is discussed in more detail as one of the methods to evaluate the influence of the uncertainty of the stress state and to evaluate the depth of rock mass yielding probabilistically.
