Severe disasters happen quite often in underground
construction projects such as at urban tunnel sites
(see Fig. 1). After such man-made disasters we
always ask the same questions: Could we have been
warned? Could this have been avoided?
In order to ensure tunnel construction projects are
safe and better managed, Kronos has been
developed and has already been successfully applied
in a number of projects. Kronos is an integrated
information system allowing for the acquisition,
checking, storage, analysis, visualisation, reporting,
and finally a warning system for tunnel project data.
Its particular advantage is that, compared to existing
solutions, all safety-relevant data produced on site
(e.g. monitoring data) is integrated into one single
data management system and utilized by most
modern and efficient alarm functions. This makes
possible the automatic execution of complex
monitoring and alarm processes including
thousands of data sources such as online monitoring
sensors and tunnelling machines. The system is
described briefly and two major European tunnel
construction sites are presented as examples of its
use to monitor and provide alarms on impending
disasters.
