Inclinometer systems are used to monitor deformation. The system includes an inclinometer casing, an inclinometer probe and a control cable, and an inclinometer readout unit.
The plastic inclinometer casing, as shown in Figure 53, is typically installed in a near-vertical borehole that passes through a zone of suspected movement. The bottom of the casing is anchored in stable ground. The inclinometer probe is used to survey the casing and establish its initial profile. The inclinometer probe consists of two servo accelerometers housed in a stainless steel body, a connector for the control cable, and two pivoting wheel assemblies. Applications
Inclinometer systems are used for the
measurement of lateral earth
movements which can occur in the following:
They are also used to measure deflections
in the walls of excavations, shafts, tunnels
and in caissons, piles and sheet piling.
Operation Ground movement causes the casing to move away from its initial position. The rate, depth, and magnitude of this movement is calculated by comparing data from the initial readings to data from subsequent readings.
