The unloading creep behavior of soft soil under lateral unloading stress path and excess pore water pressure is the core problem of time-dependent analysis of surrounding rock deformation under excavation of soft soil.
The soft soil in Shenzhen, China, was selected in this study.
The triaxial unloading creep tests of soft soil under different initial excess pore water pressures (0, 20, 40, and 60 kPa) were conducted with the K0 consolidation and lateral unloading stress paths.
The results show that the unloading creep of soft soil was divided into three stages: attenuation creep, constant velocity creep, and accelerated creep.
The duration of creep failure is approximately 5 to 30 mins.
The unloading creep behavior of soft soil is significantly affected by the deviatoric stress and time.
The nonlinearity of unloading creep of soft soil is gradually enhanced with the increase of the deviatoric stress and time.
The initial excess pore water pressure has an obvious weakening effect on the unloading creep of soft soil.
Under the same deviatoric stress, the unloading creep of soft soil is more significant with the increase of initial excess pore water pressure.
Under undrained conditions, the excess pore water pressure generally decreases during the lateral unloading process and drops sharply at the moment of unloading creep damage.
The pore water pressure coefficients during the unloading process were 0.73–1.16, 0.26–1.08, and 0.35–0.96, respectively, corresponding to the initial excess pore water pressures of 20, 40, and 60 kPa.
