Demolition and reconstruction of a railway tunnel without interruption of trafic
Abstract: The Coldrerio tunnel, 97 meters long, is located on the Milan-Zurich railway line in southern Switzerland. The existing tunnel was around 100 years old and needed a complete renovation to extend its service life. The complete renovation of the tunnel, was also necessary as part of the "Corridor 4 meters" project that FFS realized by the Swiss Confederation task. As expected from the objectives...

Influence of Soil Conditioning on the Flow Behaviour of EPB Face Support Medium
Abstract: The flow behaviour of the face supporting medium in Earth-Pressure-Balance (EPB) tunnelling is a decisive criterion for an efficient tunnel advance. The support medium needs to exhibit rather fluid properties in the excavation chamber in order to establish a quasi-hydrostatic support pressure distribution, while in the screw conveyor and on the conveyor belt a rather stiff consistency is...

Integrated data processing and simulation platform for mechanized tunneling – Showcase application on the...
Abstract: In the mechanized tunneling process a vast amount of data is collected, processed and stored in various locations and formats. An integrative strategy supporting the processing and visualization of data from different sources in connection with simulation based prognosis is becoming more and more important, especially when considering the complexity of interacting tunneling processes in...

Practical Relevance of Rheology of Foam-conditioned Sands in EPB Tunneling
Abstract: At the previous WTC 2016, the rheological characterization of soil-foam mixtures was presented by means of the slump test. Measurements from numerous slump tests were considered in analytical models enabling a derivation of rheological parameters. In this publication, the rheological analysis of soil-foam mixtures is extended to rheometer testing. By conducting experiments on different scales,...
