Yet, soil possesses some Interesting properties that relate with human beings,
Changes its properties with time
1.3 What is Geotechnical Engineering?
It is an integration of Physics, Earth Science, Solid Mechanics, Geology and
Hydrogeology. Soil Mechanics provides the theoretical basis for describing the
mechanical behaviour of earth materials. Geotechnical Engineering involves
application of theory of soil mechanics to a variety of field problems. For most
other engineering disciplines, the material properties are well-defined or can be
controlled. But, in Geotechnical Engineering, material properties are highly
variable and difficult to measure with a reasonable degree of accuracy.
Geotechnical Engineering is among the younger branches of Civil Engineering. Yet,
it has evolved over centuries.
1. Geotechnical Engineering is probably one of the most challenging
2. For a geotechnical engineer, no two days at work are going to be similar.
3. Geotechnical engineering expertise is required in a vast variety of
disciplines that includes the oil and offshore industry.
4. Being a relatively new discipline, there is ample scope for innovation.
5. For a geotechnical engineer, achieving job satisfaction is never a problem.
6. Material properties must be measured for each new construction site.
7. Remember that geotechnical engineers deal with natural materials and
there can be no quality control.
