A Modified Pressure–Sinkage Model for Studying the Effect of a Hard Layer in Sandy Loam Soil

Applied Sciences, 2021
The applicability of the typical pressure–sinkage models used to characterize the soil’s bearing properties is limited to homogeneous soils (infinite thickness) that have no hard layer. At a given depth, a hard layer can have a considerable impact on the

Evaluation of Tires Acting on Soil in Field Conditions Using the 3D Scanning Method

Agriculture, 2023
This research presents the results of tests conducted under field conditions and included measuring the footprint of tires on soil. Two agricultural tires of the same size but different internal structures were tested, 500/50R17 (radial) and 500/50-17 ...

Evaluation of Tire Footprint in Soil Using an Innovative 3D Scanning Method

Agriculture, 2023
This paper presents the results of the measurement of tire footprints in soil. The research was conducted under laboratory conditions using soil-filled cases. The research objects were two tires: a radial tire and a bias-ply tire of the same size.

Revisiting the thermodynamics of hardening plasticity for unsaturated soils [PDF]

, 2010
A thermodynamically consistent extension of the constitutive equations of saturated soils to unsaturated conditions is often worked out through the use a unique 'effective' interstitial pressure, accounting equivalently for the pressures of the ...

Field investigation of deformation characteristics and stress mobilisation of a soil slope [PDF]

, 2015
Stress mobilisation and deformation of a slope are important for engineers to carry out reliable design of retaining systems. However, most case histories reported mainly on the response of pore-water pressure (PWP), whereas knowledge about the stress ...

Evaluating the Effect of Soil Deformation Rate on the Estimation of the Energy Consumption in Soil-Tire Interactions Using the Pressure-Sinkage Equation [PDF]

Journal of Agricultural Machinery
Understanding soil deformation dynamics is critical in various fields, such as off-road vehicle mobility, agriculture, and soil mechanics. In particular, evaluating soil-tire interactions is essential for optimizing energy consumption and minimizing the ...

Soil water movement model for deformable soils [PDF]

Journal of Water and Climate Change, 2019
AbstractTo simulate the soil water movement process of deformable soils, a modified Richards model considering soil deformation (RMSD) was established. In the model, new parameters were introduced, including deformable soil porosity, deformable soil saturated hydraulic conductivity and unsaturated hydraulic conductivity of expansive soils, which varied
