Risk management in large scale underground infrastructures

Underground infrastructures can fail due to ground movements. Due to the underground nature this is difficult to detect above ground. In a collaboration of multiple research institutes a new approach has been developed to estimate the probability of failure using underground position sensors. A Proof of Principle monitoring system was developed to reduce uncertainty with respect to the feasibility of such a system. It consists of a set of interacting subsystems from different experts and takes into account uncertainty of different (sometimes correlated) subsystem variables. In this paper we describe the approach itself and its rationale. We expect his system to be used in the future for risk management. Emphasis in this paper is on the integration of subsystems and fields of expertise.
