THEMES

● Geological geotechnical investigations for tunnel design (for hard rock and soft ground tunnels, new mapping and testing techniques)

● Tunnels in urban environments (design and construction practices, interference with infrastructure networks, with existing underground structures and with buildings)

● Underground works for mining, oil & gas and other energies (design and work practices, case studies)

● Conventional and mechanized tunneling (in soft ground and hard rock, productivity and optimization, historical cases)

● Hard rock tunneling and galleries for complex situations (design and work cases, technologies)

● Ground treatment and conditioning (new conditioning techniques, historical cases)

● Archeology and architecture in underground structures (domestic and international experiences, case studies)

● Renovation and expansion of underground structures (structural recovery, retrofitting, expansions, new uses)

● Safety and operation of underground spaces (systems, technologies, regulations, risk analysis and maintenance)

● Unconventional construction (stations by secant pile wall shafts, inverted tunnel, large sections without drift)

● New design approaches (use of BIM, probabilistic calculation, seismic design, current practices and necessary developments)

● Risk management (systemic approach, contracting, insurance, probabilistic risk)
