Settlement Probe
For Vertical Settlement Profiles
Data from the Settlement Probe can reveal the depths at which set-
tlement has occurred as well as the total amount of settlement.
Settlement probes are used with telescoping inclinometer casing.
The probe is attached to a steel measuring tape and lowered through
the casing. As it passes a coupling, an arm on the probe “catches” on
the edge of the casing section.
The operator notes the reading on the steel tape, disengages the arm,
and continues lowering the probe. When the probe reaches bottom, a
mechanical action locks the arm in the closed position so it can be
withdrawn.
If bottom of casing is stable, readings are referenced to the bottom.
Otherwise readings are referenced to top of casing which must be
surveyed. Settlement is found by comparing current readings with
initial readings.
Advantages
q
Hook type probe is inexpensive.
q
Obtains settlement profile, not just single point.
Limitations
q
Requires telescoping inclinometer casing.
q
Interferes with site operations and cannot be automated.
q
USBR type probe is expensive.
q
Clumsy to read.
