The undrained shear strength of the specimens as a function of the number of freeze-thaw cycles is shown in Table 7. The values of ϕ and c for the specimen were reduced. The effective stress strength index showed the following relationship with the total stress strength index: ϕ′ > ...
Accurate assessment of undrained shear strength (USS) for soft sensitive clays is a great concern in geotechnical engineering practice. This study applies novel data-driven extreme gradient boosting (XGBoost) and random forest (RF) ensemble learning methods for capturing the relationships between the US...
Table 1 Material properties of refuse soil. Full size table The value of \(\nu_{0}\) in Eq. (7) is calculated using the following expression33: $$\nu_{0} = \nu_{{{\text{cs}}} + (\lambda - \kappa )\ln 2 + \kappa \ln \left( {OCR \times \left( {1 + \frac{{q_{0...
However, little attention has been paid to the undrained shear strength of the soils using this method. Recently, Zhang et al. [20] used the CFD-DEM method in undrained triaxial tests and compared the results with those obtained using the constant volume method. Considering the shortcomings in...
The results indicated that: (1) the increase of effective stress enhances the shear strength and deformation, and the presence of hydrates enhances the shear strength while reducing the deformation; (2) the creep strain and strain rate increase as the creep stress ratio and effective stress rise...
Laboratory values of time to peak velocity (normalizedTVP; Fig.5b) decrease when pore pressure and mobilized shear strength increase (Fig.5b; statistics in Supplementary Table2), while experimental values of peak velocity (VP, Fig.5c) show strong positive correlations with pore-pressure increase ...
