An experimental investigation on engineering properties of undisturbed loess under acid contamination

Environmental Science and Pollution Research, 2021
Even though soil acidification can cause significant destabilizing effects on various geotechnical issues, studies have rarely been conducted to determine the influence of soil structure on the impact of acid-contaminated soil. The current work aims to understand the effect of acid fluids on engineering behavior of undisturbed loess through laboratory ...

Investigation into microscopic mechanisms of anisotropic saturated permeability of undisturbed Q2 loess

Environmental Earth Sciences, 2020
The anisotropic permeability of loess is an important engineering property. To explore the microscopic mechanisms of anisotropic saturated permeability of undisturbed loess, a series of laboratory tests, including constant-head saturated permeability test, particle size analysis, and scanning electron microscope imaging, were carried out for twelve Q2 ...

Disintegration characteristics of undisturbed loess in response to train vibration frequency

Earth Surface Processes and Landforms
AbstractDisintegration fragments the loess body, causing erosion and the emergence of significant geohazards. The impact of vibrations on soil disintegration has been slightly documented; however, the contribution and mechanism of train vibration frequency in the disintegration of undisturbed loess remain unclear.

Triaxial Mechanical Testing of Undisturbed Unsaturated Loess

Soil Mechanics and Foundation Engineering, 2020
We investigated the strength and deformation characteristics of undisturbed unsaturated loess under different moisture content conditions. The results showed that the deviatoric stress intensity increases with the increase of confining pressure at the same moisture content and decreases with increasing moisture content at the same confining pressure ...

Study of the repeated collapsibility of undisturbed loess in Guyuan, China

Bulletin of Engineering Geology and the Environment, 2021
At present, the international evaluation method of loess collapsibility only evaluates loess once collapses, but some scholars have found that loess is characterized with the phenomenon of repeated collapsibility under certain conditions. To explore the characteristics of repeated collapsibility of loess and to find a simple and feasible method for ...
