What is geotechnical engineering?

Geotechnical engineering studies soil and rock behavior to design safe foundations, slopes, retaining walls, and underground structures.

Exam tip: keep SI units consistent end-to-end, write the governing relation symbolically before substituting, and sanity-check magnitude and sign.

Understand the concept

Before construction, geotechnical engineers conduct boreholes and lab tests to classify soils, estimate bearing capacity, and recommend foundation type — shallow footings, piles, or rafts.

Risk areas

Soft clay, liquefaction in earthquakes, landslides, and groundwater seepage can cause failure. Geotechnical input is critical for dams, tunnels, and high-rise buildings.
