Tunnel Monitoring

What is Tunnel Monitoring?


What can be monitored?

  • Tunnels


What can be measured?

There are a multitude of options for monitoring the changes in a Tunnel. Each project will have its own unique requirements. The structural engineers will dictate such requirements for which our experts can then provide the appropriate package.


What are the Features and Benefits?

  • Reliable data about the tunnel's behaviour & status
  • Reliable data on actual condition of the structure
  • Detect early signs of failure
  • Assist in taking specific decisions for safety measures
  • Reduce maintenance and repair costs
  • Ensure sustainability and safety of the structure
  • Assess structure's safety following a major event
  • Achieve compliance with local regulations


The most widely used packages for Tunnel Monitoring:

  1. Vibration: Structural health and behaviour
  2. Strain: Fatigue and curing related effects
  3. Displacement: Joints, cracks and differential displacements of segments
  4. Environment: Humidity and temperature

Analysis Capabilities

A typical setup will provide valuable information about the behaviour and status of the tunnel. Thresholds for acceptable changes in the structure's monitored values can be set to provide automatic notifications. After a natural disaster, at an instance valuable information about changes in the structure's behaviour can be provided. Safety decisions about the tunnel and its operation and alerts local population can be credible data and analysis.

Our knowledge of tunnels, coupled with an in-depth understanding of our instruments will provide you with an unparalleled advantage to achieve the best results for your monitoring requirements on time and on budget.

Dynamic measurements beyond and above static ones are critical requirements in tunnel monitoring as earthquakes can cause permanent damage with serious consequences. Timely and precise measurements of predefined parameters will provide the data to understand the behaviour of the structure and monitor the rate of change. A combination of static monitoring options such as deformation, displacement and settlement can be used to further provide an indication of the performance of the tunnel.
