description | Due to the programme constraints for the UX15 cavern set by CERN, it has been necessary to complete the concrete lining of the vault prior to the excavation of the bench. The vault lining is therefore being temporarily suspended from a number of pre-tensioned high capacity multi-strand tensioned ties. During excavation of the bench, additional loads will be imposed onto the vault lining due to ground displacements. In order to minimise the number of ties, the previously completed linings of the PX14 and PX16 access shafts will be used to support some of the load. Three-dimensional modelling has been undertaken to design the structures and determine the expected behaviour of this complex support system. Geotechnical instrumentation has been installed in the concrete linings and the ground to monitor loads and displacements during construction. After the cavern walls have been completed, the ties will be released. |
