Triaxial Compression Test
A triaxial compression test is used in geotechnical engineering to evaluate how a soil sample reacts under pressure from all sides. The sample is placed in a chamber, and water or air pressure is applied to the outside, simulating underground conditions. Then, a vertical force is applied until the sample deforms or breaks. This test helps determine key properties like strength, stability, and how the soil might behave under load, informing safe design for foundations, tunnels, and other structures.
