Geotechnical Forum - Winter Semester 2023/2024
For the Winter Semester 2023/2024 we would like to invite all interested listeners to the lectures of our series "Forum Geotechnik".
The event will be given on Thursday, 18:15 - 19:45 in the lecture hall BS II of the Faculty of Civil Engineering.
Afterwards, the discussion with the speakers will be continued with rolls and beer in our institute library. You are invited to join us as well.
We are very much looking forward to your coming!

Freiburg city tunnel - challenges of a city centre tunnel project
The main city centre road in Freiburg is one of the most important east-west connections in the south of Baden-Württemberg. Long traffic jams regularly occur in the urban area, with considerable negative effects on residents. The Freiburg city tunnel is intended to provide fundamental relief for the city and decouple through traffic from the city centre. The presentation will examine various aspects of the design planning, from route selection and the choice of construction methods to selected geotechnical aspects. Particular attention will be paid to the challenges of planning a major project in a city centre environment and the associated complex boundary conditions.

Claystones are difficult fellows - an attempt to better understand their behaviour in tunnel construction
Claystone is known as a challenging subsoil in tunnelling. This is particularly due to their relatively low and variable strength, their usually pronounced anisotropy and their time-dependent and hydromechanically coupled behaviour. Their suitability as a host rock for the disposal of radioactive waste in particular has brought them into the focus of the repository industry in recent decades and their geomechanical behaviour has since been investigated even more intensively. The challenges in dealing with clay rocks begin with sampling and storage and extend across all scales from their experimental characterisation and process understanding to numerical modelling and its validation. The lecture provides insights into selected geomechanical aspects and their special significance for the excavation of tunnels.
