Macro–micro deformation characteristics of undisturbed loess under different hydraulic paths [PDF]

open access: yesScientific Reports
Understanding the mechanical behavior of undisturbed loess under different hydraulic paths (wetting followed by loading(W-L) and loading followed by wetting(L-W)) is critical for geotechnical engineering in loess regions.

Evolutional law and elastoplastic constitutive model of structural loess considering moisture contents. [PDF]

open access: yesPLoS ONE
The deformation properties of natural undisturbed loess are intricately linked to its structural qualities. Structural characteristics can markedly improve soil stability, allowing structured loess to sustain a greater void ratio than disturbed loess ...

An Experimental Study of Mineral and Microstructure for Undisturbed Loess Polluted by Landfill Leachate

open access: yesKSCE Journal of Civil Engineering, 2018
To investigate the shear strength and microstructure of undisturbed loess polluted by landfill leachate, a series of laboratory tests were carried out to determine the shear strength, mineral composition, surface morphology, particle size distribution and pore characteristics of the loess.

A new method for predicting the shear strength of loess based on moisture content and large and medium pore volume [PDF]

open access: yesScientific Reports
The Loess Plateau region faces persistent geohazards that critically threaten both ecological stability and human safety, largely due to the distinct metastable microstructure of loess, which evolves under changing environmental conditions and governs ...

Discrete element simulation study on micromechanical characteristics of undisturbed and remolded loess in biaxial test

open access: yes地质科技通报, 2021
Loess is a special granular material, and its mechanical properties are determined by the microscopic structure of granules. The undisturbed and remolded loess have different mechanical properties due to the difference in structure. In order to solve the

Correlation between soil-water characteristic curve and collapsibility in undisturbed loess

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao
This study investigates the correlation between the soil-water characteristic curve (SWCC) of undisturbed loess and its collapsibility. Undisturbed loess soil samples, obtained from depths up to 30 meters below the surface in Chang’an District, Xi’an ...

A critical state model for structural loess considering water content

open access: yesRock and Soil Mechanics, 2022
According to the structural evolution behaviors of undisturbed loess with different initial water contents, and based on the theory of critical-state soil mechanics, a critical-state constitutive model is proposed to describe the structural evolution and

Influence mechanism of structure on shear mechanical deformation characteristics of loess-steel interface.

open access: yesPLoS ONE, 2022
The mechanical properties of loess-steel interface are of great significance for understanding the residual strength and deformation of loess. However, the undisturbed loess has significant structural properties, while the remolded loess has weak ...
