Abstract: With the improved triaxial equipment, a series of K0 consolidation and undrained shear tests have been carried out to study the unloading deformation properties of a typical soil in Tianjin urban area. According to the experimental results, the stress-strain curve is a hyperbola and has obvious normalization character. The initial tangent modulus obtained is directly proportional to the initial confining pressure.

Key words: experimental studies, unloading stress paths, deformation properties, normalization
