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

Pressão de preconsolidação e intervalo hídrico ótimo como indicadores de alterações estruturais de um latossolo e de um cambissolo sob cana-de-açúcar Preconsolidation pressure and least limiting water range as indicators of structural changes of a latosol and a cambisol under sugarcane

Revista Brasileira de Ciência do Solo, 2008
A identificação dos impactos da colheita mecanizada da cultura da cana-de-açúcar sobre a estrutura do solo em diferentes classes pode-se tornar uma importante estratégia de manejo para a minimização dos efeitos da compactação.

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.

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 ...

Compressibility and water availability in Albaqualf soils under different deployment times in no-tillage

Scientia Agricola
: The southern Brazilian lowlands have been historically used for flooded rice cultivation. Over time, heavy machinery and intensive tillage practices have resulted in soil structure disruption, soil compaction, higher production costs and lower ...

Soil precompression stress assessed from strain‐stress data in linear scale: The need for a physically based approach

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract State‐of‐the‐art models for soil compaction express soil strength by the so‐called precompression stress. The idea is to avoid stresses higher than those previously exposed to the soil. However, the quantification of soil precompression stress generally implies a problematic logarithmic transformation of the applied stress.

Compactação de solos cultivados com cana-de-açúcar: I -modelagem e quantificação da compactação adicional após as operações de colheita Compaction of soils cultivated with sugarcane: I - modeling and quantification of the additional soil compaction after harvest operations

Engenharia Agrícola, 2010
A colheita mecanizada da cana-de-açúcar, quando realizada em épocas da safra em que o solo se encontra com conteúdos inadequados de água, tem sido responsável pela compactação do solo e a redução da produtividade nos ciclos posteriores da cultura.
