Research on a Novel Counterweight‐Type Retaining Pile and Structural System Capable of Constraining Lateral Displacement

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Conventional retaining structures mainly emphasize overall stability, yet their efficacy in restricting displacement and deformation remains relatively limited. To meet the engineering demand for high embankment stabilization and lateral deformation control in highway projects, this study proposes a novel retaining structure based on classical earth ...

Mechanism and Modeling of Strength Loss for Saline Aeolian Sand: A Deterioration Framework Under Freeze‐Thaw Cycles

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
In desert edge areas, the degree of soil salinization is high, and aeolian sand contains a significant amount of fines. As fine‐grained aeolian sand is more susceptible to temperature, moisture, and salt influences compared to pure aeolian sand, its use in road construction may induce roadbed diseases at later stages.
