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.

Data-driven Design of New Materials and Structures
Prof. Miguel A. Bessa (TU Delft, The Netherlands)

Prof. Miguel A. Bessa form the TU Delft, The Netherlands, will hold a guest lecture in the framework of SFB 837 about 'Data-driven Design of New Materials and Structures'.

A data-driven computational framework combining Bayesian machine learning for imperfection sensitive quantities of interest, uncertainty quantification and multi-objective optimization is developed to analyze and design new materials and structures. This talk intends to demonstrate the generality of the proposed framework, highlighting key challenges and possible solutions illustrated by three different design problems: toughening composite materials by tuning the plastic behavior of the constituents, improving collapse behavior of ultra-thin satellite structures with uncertain ultimate buckling strength, and finding unprecedented properties by exploring a new material concept.

DFG Funding Atlas 2018: RUB’s civil engineers take 1st place with SFB 837 once again


On 5th July 2018, the eighth edition of the German Research Foundation’s Funding Atlas was published. It lists the figures for publicly funded research in Germany for the year 2018. As in the 2015 edition, Ruhr-University Bochum holds the top position in the field of civil engineering/architecture. It thus occupies a leading position, ahead of other universities involved in the excellence initiative, such as RWTH Aachen.

The Collaborative Research Center SFB 837 has made a significant contribution to the excellent result: the funding volume that Bochum researchers raised between 2014 and 2016 amounted to 10 million euros in this area. Compared to the 2015 edition, this reflects an increase of around one million euros.

With a total funding of 14.3 million euros, the Ruhr-University Bochum was still in sixth place in 2015. In the current edition, it is now in second place with a funding volume of 20.5 million euros.

Special Issue on Computing with Polymorphic Uncertain Data


A Special Issue on Computing with Polymorphic Uncertain Data has been published in the International Journal of Reliability and Safety. The Special Issue has been edited by Steffen Freitag (Ruhr University Bochum), Rafi L. Muhanna (Georgia Institute of Technology) and Robert L. Mullen (University of South Carolina) and is based on the 7th International Workshop on Reliable Engineering Computing (REC 2016) held at Ruhr University Bochum in June 2016. The 11 papers of this special issue present new developments for the consideration of stochastic and non-stochastic uncertainties in various engineering and associated disciplines.
