Monitoring Objective
Bridges and tunnels experience gradual geometric change together with dynamic effects from construction, traffic and the environment. Separate whole-structure movement from local response at critical details.
Monitoring Parameters
- Tunnel convergence and longitudinal settlement
- Pier, bearing and member tilt
- Vibration frequency, amplitude and acceleration
- Crack and expansion-joint movement
Typical Configuration
The RT-1010 tracks continuous deformation and tunnel convergence, while the RT-1030 measures local tilt and vibration together. The draw-wire RT-1060 covers longer movement; the compact rod-type RT-1080 suits cracks and expansion joints.
Deployment Considerations
Mounting brackets require a rigid connection to the monitored structure and protection from construction impact. Record sensor axes, initial readings and installation photographs consistently.
FAQ
Why measure tilt and vibration together?
Synchronized data separates gradual attitude change from short dynamic events and shows whether an angle change coincided with significant vibration.
