1 INTRODUCTION
Encardio-rite model EAN-90M tilt meter is suitable for
monitoring inclination and vertical rotation of structures. It is a
high resolution tilt meter, is rugged in construction and has
excellent temperature stability.
Tilt change in a structure may be caused by construction activity
like excavation, tunneling or de-watering that may affect the
ground supporting the structure. Change in tilt could also result
from loading of the structure, such as loading of a dam during
impoundment, loading of a diaphragm wall during excavation or
loading of a bridge deck due to wind and traffic. Data from the tilt meter provides early warning of
threatening deformations, allowing time for corrective action to be taken or if necessary for safe evacuation
of the area.
1.1 Applications
EAN-90M tilt meter is widely used in following applications:
Monitoring vertical rotation of retaining walls.
Monitoring inclination and rotation of dams, piers, piles and other structures.
Monitoring stability of structures in landslide areas.
Monitoring tunnels for convergence and other movement.
Monitoring safety of structures around zones of excavation or tunneling.
Monitoring deflection in bridges and struts under different loading conditions.
