Geotechnical engineering uses the principles of soil mechanics and rock mechanics to investigate subsurface conditions and materials. Geotechnology plays a key role in all civil engineering projects built on or in the ground, as well as in the assessment of natural hazards (earthquakes, landslides, sinkholes, etc.), the monitoring of site conditions, and structural design.
The following geophysical methods can be used for geotechnical engineering:
