Numerical modelling is one of the major tools for design of excavations in rock. The Institute has experienced civil and mining engineers with expertise in providing solutions to varied problems related to excavations in rock. Anticipated rock mass behaviour around an excavation can be reliably predicted using the latest FEM and BEM numerical modelling codes (software based on discrete and continuum element methods) available at the Institute. We undertake the stress analysis and support design for tunnels, caverns and large underground multiple excavations.

Capabilities: With experience gained over the years in the analysis and design of underground excavations using numerical modeling, we offer solutions in the following areas:

• Analysis and design of caverns and tunnels
  
  
• Rock liner interaction analysis for pressure shafts
  
  
• Design of supports (rock bolts and SFRS)
  
  
• Coupled thermo-hydro-mechanical analysis of the rock mass
  
  
• Dynamic analysis including seismic and liquefaction behaviour
  
  
• Stability analysis of earth dams and slopes
  
  
• Instrumentation for strata and support system monitoring
