| Abstrait: |
The Diabolo-project aims to improve the northern railway connectivity of Brussels Airport by 2012. As an important part of this project, a 1084 m long twin tube tunnel was shield driven below the airport runways and taxi-lanes using the mixshield method. During construction of both tunnel shafts, measurements have been carried out at several cross-sections of the tunnel lining. Each monitored ring was equipped with several strain gauges, distributed across the ring perimeter. The practical implementation of the strain gauges and measurement apparatus is explained and the first preliminary results of the completed measurements are presented. Finally a comparison will be made between the strain gauge measurements and extensive ovalisation measurements carried out at identical cross-sections. |
