triaxial compression test
A geotechnical engineering test where a cylindrical soil or rock specimen is subjected to controlled confining pressure and axial load to measure shear strength and stress-strain behavior.
The triaxial compression test is widely used in geotechnical engineering.
The shear strength of this soil was determined by a triaxial compression test.
Compound of 三軸 (triaxial) + 圧縮 (compression) + 試験 (test). A technical term formed from Sino-Japanese elements.
