Smach strong motion accelerograph
Planning a performance monitoring programmein an essential component of succesfull tunnelconstruction. Tunnel monitoring is reccomended todetermine the behaviour of the surrounding soilduring excavation, to ensure the stability and thesafety of the structure.
Criteria of instrument selection:
•Reliability of measurements
(resolution,accuracy and repeatability)
•Long-term stability and instrument longevity
•Easy of automation for real time monitoring
•Efficient data management
TUNNEL MONITORING INSTRUMENTATION
Well-planned Monitoring Program
Developing Stage
Determine the purpose of instrumentationSelect the parameters to monitor
Define factors which influence measurementsPrepare budget
Select instruments and their locationsPrepare specifications and instrument procurements
Plan instrument installation and maintenancePlan data management and reporting
Execution Stage
Procure and install instrumentsMaintain instruments and readouts
Collect measurements and manage dataCompare data with design values
Interpret data Plan a corrective instrument implementation
Convergence tape extensometer Concrete hydraulic stress cells Borehole extensometer
Electrical piezometers
