Abstract
It is shown by the results of stress path tests in soft clay that the unloading modulus of soft clay is highly stress path dependent. Stress path testing technique was adopted in this paper to investigate the deformation characteristics of the soft clay including very soft clay, very soft silty clay, and grey clay in Shanghai region under a series of unloading stress paths. The relations between unloading modulus of Shanghai soft clay and stress paths are established.
