Abstract

The European Centre for Nuclear Research (CERN) is a large underground laboratory and it is home to two large particle accelerators, including the «Large Hadron Collider» (LHC). The particles travel at the speed of light through a series of tunnels which must comply with the high serviceability requirements. However, the underground facilities have expanded over a period of 40 years with new tunnels, shafts and caverns. Structural ageing and deterioration of the infrastructure can alter the drainage conditions around tunnels and this can cause, in turn, excess deformation of the tunnels and serviceability issue for the particle accelerators. A remote monitoring system based on distributed fibre-optic strain sensing technology has been implemented in some of the concrete-lined tunnels in order to gain insight in the long-term mechanical behaviour of the underground system. This paper presents the results of the monitoring programme and the results show a slow development of ovalisation of the tunnel over a period of three years.
