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

Determining soil water characteristic curve of lime treated loess using multiscale structure fractal characteristic

open access: yesScientific Reports, 2020
Soil–Water characteristic Curve (SWCC) is meant to describe the mechanical behavior of unsaturated soil. The present paper focuses on the internal multi-scale microstructure of Xining untreated loess and lime-treated loess with the use of scanning ...

Are Chinese loess deposits essentially continuous? [PDF]

open access: yes, 2007
We conducted a paleomagnetic examination of the last glacial loess of three representative profiles along an east-west transect in the central Loess Plateau in order to assess the continuity of Chinese loess. The results show that the Xifeng and Luochuan

Experimental study on seismic subsidence characteristics of structural loess under cyclic torsional shear

open access: yesYantu gongcheng xuebao, 2020
The undisturbed loess has significant structural and dynamic vulnerability. Under the earthquake, the dynamic shearing action destroys the original structure of loess.

Parent materials: Loess

open access: yes, 2023
Loess is commonly defined as a distinct body of mainly wind-blown silt and covers c. 10% of the Earth's surface, mainly in the temperate zone. Silicate silt predominates over carbonate, clay and some fine sand, making loess a favorable soil parent ...

Deterministic processes dominate soil microbial community assembly in subalpine coniferous forests on the Loess Plateau [PDF]

open access: yesPeerJ, 2019
Microbial community assembly is influenced by a continuum (actually the trade-off) between deterministic and stochastic processes. An understanding of this ecological continuum is of great significance for drawing inferences about the effects of ...

The hidden influence of protozoa on hydrophyte-epiphytic bacterial communities

open access: yesGlobal Ecology and Conservation
Plants and their epiphytic microorganisms synergistically participate in biogeochemical cycling and pollutant removal in wetlands, but the assembly mechanisms of epiphytic microbial communities remain unclear.
