Experimental Study on the Modification of Loess by Montmorillonite: Insights From Electrical, Thermal, and Mechanical Properties

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The large pore structure of loess is a key factor governing the geotechnical environment in northwestern China. It not only dominates the mechanical strength of geotechnical bodies in this region but also significantly regulates their thermoelectric response characteristics.

The Tensile Strength of Loess in Northwest China by Unconfined Penetration Test and the Distinct Element Simulation

Advances in Civil Engineering, 2021
The unconfined penetration test (UP test) is one of the indirect methods to measure the tensile strength of soils. Through a series of UP tests of undisturbed and remolded loess, the split angle (α) of the wedge body which was shaped in the process of ...

Effects of Fine‐Grained Particles and Sodium Chloride Solution on Physical Properties and Residual Strength of Granite Residual Soils: An Experimental Study

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Stability analyses of earth structures composed of granite residual soils (GRSs) are consistently essential, particularly under significant vibrational loading. In these analyses, it is stressed that the residual strength ought to be applied instead of peak strength.

Effect of Freeze–Thaw Action on Mesostructure of Ecological Fiber Reinforced Loess

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Traditional chemical additives inevitably pollute, damage, and destroy the ecological environment and natural resources while simultaneously addressing the requirements of engineering construction in loess areas. Additionally, freeze–thaw cycles exert a substantial influence on the long‐term durability of engineering structures located in areas with ...

Mechanical Characterization of Unsaturated Loess and Numerical Simulation of Slope Stability Under Freeze–Thaw Cycles

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
The soils in the eastern region of Qinghai, China, are characterized by typical unsaturated loess with poor engineering properties, rendering them susceptible to geological disasters such as landslides. To investigate the mechanical properties of these soils, triaxial and direct shear tests were conducted, followed by simulations of deformation and ...
