1. On reliability-based design of rock tunnel support
Abstract : Tunneling involves large uncertainties. Since 2009, design of rock tunnels in European countries should be performed in accordance with the Eurocodes. The main principle in the Eurocodes is that it must be shown in all design situations that no relevant limit state is exceeded. READ MORE

2. Reliability-based design of rock tunnel support
Abstract : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. READ MORE

3. Geotechnical risk management using the observational method
Abstract : There have been many cost overruns, time delays and quality problems reported from geotechnical engineering projects around the world during recent decades. Many of the reported problems are associated with risks related to the geotechnical conditions. READ MORE

4. Analysis of Excavation Damage, Rock Mass Characterisation and Rock Support Design using Drilling Monitoring
Abstract : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. READ MORE

5. Freezing Temperature Flows in Railway Tunnels and its Consequence on the Rock Supporting Structure, the Rock and the Reinforcing Elements
Abstract : Water in the surrounding rock mass flows into the tunnel via naturally occurring joints and via cracks caused by the blasting used to excavate the tunnel. The most common method in Sweden to reduce or prevent leakage problems are first and foremost the use of grouting. READ MORE
