What are all experiments done in the geotechnical laboratory? Explain sieve analysis, direct shear test, compaction test.

Question

Accepted Answer

Geotechnical laboratory experiments include sieve analysis, direct shear test, and compaction test.

Sieve analysis is used to determine the particle size distribution of soil samples.
Direct shear test measures the shear strength of soil samples under different loads and normal stresses.
Compaction test is used to determine the maximum dry density and optimum moisture content of soil samples.
Other experiments may include triaxial shear test, consolidation test, and permeability test.
Results from these experiments are used to design foundations, retaining walls, and other geotechnical structures.
