Mechanical properties of saturated remolded loess under different stress paths

open access: yesShuiwen dizhi gongcheng dizhi, 2022
The mechanical properties of soil often vary with stress state and stress paths. In order to investigate the mechanical properties of saturated soil under vertical loading and constant shear stress path, saturated remolded loess samples are prepared ...

A modified elastoplastic damage structural constitutive model of unsaturated Q3 undisturbed loess [PDF]

open access: yesScientific Reports
The weakening of loess structure under hydro-mechanical effect is an important reason for collapsible deformation of loess. Therefore, when establishing the constitutive model of unsaturated loess, it is necessary to consider the influence of loess ...

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

A New Method for Evaluating the Homogeneity and Structure of Remolded Loess Samples with the Air Permeability Coefficient

open access: yesApplied Sciences, 2022
The uniformity of remolded loess samples prepared in the laboratory directly determines the reliability of various test results. While many tests have been designed to reflect the properties of undisturbed loess, there are obvious structural differences ...

Effect of freezing-thawing cycles on mechanical properties and microscopic mechanisms of loess

open access: yesShuiwen dizhi gongcheng dizhi, 2021
Qinghai is located in a permafrost region, which belongs to the continental climate zone of the the Qinghai-Tibet Plateau. At the same time, freezing-thawing cycles are common destructive factors for roadbeds and foundations.

Segmental Modification of the Mualem Model by Remolded Loess [PDF]

open access: yesMathematical Problems in Engineering, 2017
The measured diffusion coefficient and soil‐water characteristic curve (SWCC) of remolded loess were used to modify the Mualem model for increasing its accuracy. The obtained results show that the goodness of fit between the Mualem model and the variable parameter‐modified Mualem method comparing with the test results was not high.
