On the evaluation of pre-consolidation pressure of undisturbed saturated clays

HBRC Journal, 2017
The objective of this research was to show the effect of sample disturbance on the values of pre-consolidation pressure бc by using Schmertmann method. A prediction of бc form pocket penetrometer is also achieved.

Effect of strain rate on consolidation behavior of Ariake clay and selection of the suitable strain rate

Yantu gongcheng xuebao, 2017
The effect of strain rate on the consolidation behavior of Ariake clay is investigated by the constant rate of strain (CRS) consolidation tests under different strain rates, and the suitable stain rate in CRS consolidation tests is discussed based on the

Physical properties of a Brazilian sandy loam soil after the traffic of a military vehicle M113 BR [PDF]

Revista Brasileira de Ciência do Solo, 2020
Soil physical properties can be changed after vehicle traffic, especially by heavy military tracked vehicles. The Santa Maria military Instruction Field, where the experiment was carried out, is currently the most used area for armored tracked vehicles ...

Laboratory and field determination of preconsolidation pressures at Gloucester

Canadian Geotechnical Journal, 1983
In recent literature several special test methods have been proposed to measure the preconsolidation pressure of a compressible clay soil. Five methods, in addition to the conventional oedometer test, were applied to the marine clays from the Gloucester test site.

One-Dimensional Large-Strain Nonlinear Consolidation of Overconsolidated Clays with a Threshold Hydraulic Gradient

Advances in Civil Engineering, 2018
The existence of the threshold hydraulic gradient in clays under a low hydraulic gradient has been recognized by many studies. Meanwhile, most nature clays to some extent exist in an overconsolidated state more or less.

Soil compaction due to forest harvest operations Compactação do solo em conseqüência das operações de colheita florestal

Pesquisa Agropecuária Brasileira, 2007
The objective of this work was to determine, through the use of the bearing capacity model, the traffic effects of the forest harvest operations on the preconsolidation pressure (sigmap), during one cycle of the eucalyptus plantation.

Capturing Complex Rate‐Dependent Behaviors of Saturated Clays: A Fractional Consistency Kinematic Hardening Viscoplastic Approach

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3281-3296, 10 June 2026.
ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...
