Background

The inclinometer is typically installed in a vertical bore hole that passes through the unstable earth formation to the lower stable earth formation. The deformation of the inclinometer was observed using a vertically movable inclinometer probe, control cable, and readout. The first observation can establish an initial profile of the displacement of the inclinometer. Subsequent observations will show the change in section displacement as the inclinometer moves. During observation, the probe moves from the bottom of the inclinometer to the top, pauses at a half-meter interval and measures the inclination. The inclination of the probe is measured by a servo accelerometer. The inclination may be converted into a lateral displacement. Comparing the current and initial observations allows the amount of change in lateral offset to be determined, indicating the displacement of the formation. And drawing the variation of the offset to obtain a displacement sectional diagram.
