6.18.2. Tunnels

Try these first

1. 1.

   What is the purpose of convergence sensors?

   Hint

   Think about tracking structural shape.

2. 2.

   Why do we monitor humidity in tunnels?

   Hint

   Consider the effects of water on construction.

3. 3.

   What do convergence sensors measure?

   • Temperature changes
   • Structural deformation
   • Water levels

   Hint

   Think about the shape and form.

4. 4.

   True or False: Humidity sensors are essential for detecting structural stress in tunnels.

   • True
   • False

   Hint

   Focus on the purpose of humidity sensors.

5. 5.

   Design a sensor monitoring plan for a new tunnel project, detailing the types of sensors required and their specific functions.

   Hint

   Consider environmental and structural needs when designing the plan.

6. 6.

   Analyze a situation where sensor failure occurred in a tunnel and suggest how this could be prevented in future projects.

   Hint

   Focus on maintenance and checks during planning.
