Experimental Study on Noncoaxial Characteristics of Saturated Remolded Loess [PDF]
Advances in Civil Engineering, 2020 In practical engineering, if the influence of noncoaxial stress and strain is not considered, part of soil deformation will be ignored, resulting in the structural design which is not safe enough.

Effect of Sodium Chloride Concentration on Saturated Permeability of Remolded Loess [PDF]
Minerals (Basel, Switzerland), 2020 Loess contains many sodium and chloride ions that can easily be leached when seepage occurs, thus affecting the mechanical properties of loess. This study investigated a series of sodium chloride solution concentrations to explore their influence on the permeability of remolded loess, as well as the underlying mechanism of such.
