Tilt in any structure can be caused by various construction activities like excavation, tunneling, or de-watering that may negatively affect the ground that supports the structure.
Tilt changes can also occur due to the loading of the structure, such as the loading of a dam during impoundment, a diaphragm wall during excavation, or, a bridge deck due to wind and traffic.
The data captured from the tilt meter gives an early warning of threatening deformations, allowing time for corrective action.
Applications of Tilt Meter and Beam Sensors:
- Monitoring vertical rotation, deflection, and deformation of diaphragm & retaining walls.
- Monitoring inclination and rotation of dams, piers piles, etc.
- Monitoring structures for the effects of tunneling and excavation.
- Monitoring the stability of structures in landslide and earthquake-prone areas.
- Monitoring tunnels for convergence and other movements.
- Evaluating the performance of bridges & struts under load.
