Deformation Monitoring

So what is deformation monitoring?

From Wikipedia, the free encyclopedia
http://en.wikipedia.org/wiki/Deformation_Monitoring

Deformation monitoring is the systematic measurement and tracking of the alteration in the shape or dimensions of an object as a result of the application of stress to it. Deformation monitoring is a major component of logging measured values that may be used to for further computation, deformation analysis, predictive maintenance and alarming.

Deformation monitoring is primarily related to the field of applied surveying, but may be also related to the civil engineering, mechanical engineering, plant construction, soil and rock stability mechanics.

According to [2], deformation surveys are mainly carried out to investigate crustal movement, slope stability, glacier and shelf ice movement, ground subsidence and deformation of man-made engineering structures.

The determination consist from design, measurement and analysis stage [3].

The measurement technique generally divided into geodetic and geotechnical/structural methods.

a) Geodetic method: conventional & terrestrial survey and space-based method. Global information
b) Geotechnical/structural: Local information (strain gauge, piezometer and inclinometer). Short distance and small area coverage
