An Improved Model to Describe the Creep Behavior of Soft Soil
The creep characteristics of soft soil from the Luogang District of Guangzhou (China) were analyzed using a laboratory-based direct shear creep apparatus. Normal stress was applied to the samples, and the corresponding displacement was monitored under constant horizontal shear stress. The results show that at lower shear stress levels, Luogang soft soil shows the characteristics of attenuated stable creep. At higher shear stress levels, the creep curve enters a phase of constant creep. The constant creep rate increases with increasing shear stress. We developed a nonlinear creep constitutive model by combining the nonlinear creep stress-strain isochronous curve of the soft soil with theoretical and empirical models. This model will be useful for devising strategies to prevent landslides during sudden natural disasters.
