Meanings
-
An electromechanical device for measuring changes in length of an object undergoing stress.
For the ground, that means using three primary types of equipment:
■ Extensometers to look for ground heave - the upwards movement of soil, which can occur at any stage. It is essentially the opposite of erosion and is often associated with clay-type soils which swell when wet.
■ Inclinometers, which measure slope movements.
■ Piezometers to measure water levels.
