What is a soil sample?

A soil sample is material collected from the ground for laboratory testing and analysis.

Why are soil samples collected?

They help determine soil composition, strength, compressibility, and other engineering properties.

Common soil types include clay, sand, gravel, silt, peat, and bedrock.

Bearing capacity is the maximum load a soil can safely support without excessive settlement or failure.

It is evaluated through field investigations, borehole data, laboratory testing, and engineering analysis.

It helps engineers design foundations that safely support structures.

Laboratory testing involves analyzing soil samples to determine their physical and mechanical properties.

Common tests include grain size analysis, moisture content, Atterberg limits, compaction testing, and strength testing.

The SPT is a field test used to evaluate soil density and strength during drilling operations.
