Abstract:
Useful numerical simulation of shafts, crushers and other infrastructure excavations is amongst the most challenging of rock mechanics problems. The mechanical installations and concrete forms are usually designed with tolerances to deformation that are very low by mining standards and the effects of out of specification ground movements can be very costly. The high costs of problems in these excavation sets a very high standard of analysis for the rock mechanics engineer, yet modelling of these items is often treated as an after thought. In this paper, fitness-for-purpose requirements for analysis of critical infrastructure excavations are discussed in terms of the capabilities of modern, commercially available analysis packages and computational capacities. Probabilistic assessments of excavation performance and direct simulation of excavation deformation is discussed in detail. It is concluded that contemporary advances in simulation capabilities have led to a new minimum standard of analysis for critical infrastructure excavations.
