Experiment Study of Lateral Unloading Stress Path and Excess Pore Water Pressure on Creep Behavior of Soft Soil

Figure 3

Unloading creep deviatoric stress-strain curves of soft soil under different initial excess pore water pressure (consolidation confining pressure 100 kPa). (a) Initial excess pore water pressure u₀ = 0 kPa. (b) Initial excess pore water pressure u₀ = 20 kPa. (c) Initial excess pore water pressure u₀ = 40 kPa. (d) Initial excess pore water pressure u₀ = 60 kPa.
