Experimental Study on the Anisotropic Properties of Undisturbed Loess
Applied Mechanics and Materials, 2011Loess has been subjected to long-term deposit, geological structure and weathering under the condition of self-weight and above covered load. Accordingly, it would result in many vertical joints and differences in mechanical response and deformation properties for vertical and transverse.

Effects of intrinsic anisotropy on the dynamic behaviour of undisturbed loess
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2019To investigate the effects of the relative orientation between a sample's principal axes of anisotropy and the principal stress axes on the dynamic behaviour of undisturbed loess, samples with axial inclinations 30° and 90° relative to the horizontal were prepared.

Effect of pre-dynamic loading on dynamic liquefaction of undisturbed loess
Bulletin of Earthquake Engineering, 2020Earthquakes occur frequently in the Loess Plateau area, which result in damage to loess due to the disturbance of multiple cyclic loading. In this paper, the historical earthquake process is simulated by pre-dynamic loading treatment on undisturbed loess samples. Then cyclic tests are carried out on these treated samples to study the later liquefaction

Effect of pre-dynamic loading on static liquefaction of undisturbed loess
Soil Dynamics and Earthquake Engineering, 2020Abstract Static liquefaction can make the loess unstable when the shear stress subjected to a monotonic loading exceeds the undrained peak shear strength of undisturbed saturated loess. It is a phenomenon in the failure of soil deposits caused by a sudden increase of pore water pressure accompanied by large deformations and loss of effective stress ...

Inherent Anisotropy of an Undisturbed and Compacted Loess Soil
2015This work discusses the result of an experimental study on inherent anisotropy of the loess soil found at Córdoba, Argentina. A cubical true triaxial device provided with flexible boundaries was used and the samples were subjected to an isotropic compression stress path.

The internal erosion process and effects of undisturbed loess due to water infiltration
Landslides, 2020Internal erosion is a complex phenomenon that is one of the main risk factors to soil destruction. Its occurrence is mainly due to water infiltration and can cause slope instability. “Karst soil” is a type of loess with special soil and water sensitivity that makes it prone to landsliding. The processes of internal erosion include transport erosion and

Microstructural Evolution of Undisturbed and Remoulded Loess Under Triaxial Compression
Geological JournalABSTRACT The undisturbed and remoulded loess samples were subjected to the unconsolidated‐undrained triaxial compression test, imaged using scanning electron microscopy before and after the triaxial compression test and analysed with the image‐processing software Image‐Pro Plus to extract pore characteristics from the loess images ...
