Constitutive Model of Lateral Unloading Creep of Soft Soil under Excess Pore Water Pressure

Figure 3

Stress-strain isochronous curve of soft soil unloading creep under different excess pore water pressures, u, of (a) 0 kPa, (b) 20 kPa, (c) 40 kPa, and (d) 60 kPa. Note: (σ1σ3)s is the yield deviatoric stress of soft soil; (σ1σ3)max is the maximum partial stress that the soft soil can withstand.
