Workshop Herausforderung Tunnelbau 2018: Lectures by Prof. Konrad Bergmeister and Dipl.-Ing. Felix Amberg


The use of underground space is a key factor for sustainable development of both industrial as well as emerging and developing countries. Underground transalpine transport links, the tendency for larger diameters, difficult geological conditions or high groundwater pressures pose major challenges for tunneling and drilling technologies.


The workshop series ,Herausforderung Tunnelbau 2018' will once again be dedicated to an exciting and up-to-date topic this year.

Prof. Konrad Bergmeister will talk about the Brenner Base Tunnel and its geotechnical and tunnel engineering challenges in the construction of an emergency stop in Innsbruck.

The lecture by Dipl.-Ing. Felix Amberg focuses on a 100 km long tunnel between Helsinki and Tallin, whose structural and economic aspects represent the next generation of long tunnels.

Long-term Tunnel Behaviour and Ground Movements after Tunnelling in Clayey Soils
Dr. Zili Li (University College Cork, Republic of Ireland)

Dr. Zili Li form the University College Cork, Republic of Ireland, will hold a guest lecture in the framework of SFB 837 about 'Long-term Tunnel Behaviour and Ground Movements after Tunnelling in Clayey Soils'.

Long term ground movements above a tunnel may continue to increase with time after tunnelling in clayey soils as the tunnelling-induced excess pore water pressures dissipate, whilst the changing earth pressure acting on the tunnel leads to further tunnel deformation during consolidation. Furthermore the tunnel itself introduces new drainage conditions; that is, depending on the drainage condition of the tunnel lining, the effective stresses around the tunnel change with time, inducing further soil consolidation. A seepage rate from low permeability clayey soil is often very small and the groundwater seeping into the tunnel can evaporate quickly. Although a tunnel may look impermeable because the surface looks dry, it is possible that the tunnel drainage conditions are actually permeable.

This lecture will summarise the investigation of soil-tunnel consolidation interaction, particularly focusing on ground surface movements and tunnel lining deformation in the interest of engineering concerns. Analysis results show that tunnel lining permittivity relative to the permeability of the surrounding ground plays an important role on both long-term ground movements as well as tunnel lining behaviour. The findings published in literature are reviewed step by step starting from a single tunnel, twin tunnels to complex cross passage structures. The mechanisms of tunnelling-induced soil consolidation for these structures are identified and, where applicable, possible engineering methodologies to assess the magnitude of long-term ground surface settlements and tunnel lining loads are proposed.

Hybrid lining segments for modern tunnel constructions - Intelligent use of steel fiber reinforcement


The application of steel fiber reinforced concrete for precast tunnel lining segments is increasingly gaining importance for several years.

The workshop "Hybrid lining segments for modern tunnel constructions - Intelligent use of steel fiber reinforcement" mainly aims to present and discuss recent advances and developments both within and outside the SFB 837.
Furthermore, its objective is to give an overview on practical experiences regarding the use of steel fiber reinforced concrete for segmental linings. In particular aspects of material, production, robustness, durability and sustainability are in the focus of the workshop.
