Recent Advances in Soil Stabilization and Reinforcement: A Comprehensive Review of Emerging Technologies

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The rapid increase in the global population has intensified the need for residential areas and civil infrastructure, ultimately leading to construction in areas with less desirable geological conditions. This underscores the necessity for soil improvement. With increasing public concern for environmental issues and the urgent goal of achieving net‐zero

Effect of Vertical Spacing Between Prefabricated Horizontal Drains on Vacuum Preloading of Dredged Slurry

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The vacuum preloading combined with prefabricated horizontal drain (PHD) is an effective foundation treatment method for high‐water‐content dredged slurry. As the key design parameter of PHD vacuum preloading technology, the vertical spacing of PHD directly affects dredged slurry consolidation efficiency. However, its optimal value has not been clearly

Experimental, Numerical, and Analytical Studies of the Uplift Behavior of Mini‐Piles in Moistened Loess Foundations With Parameter Sensitivity Analysis

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Mini‐piles are increasingly employed as foundations for transmission towers owing to their ease of construction and high uplift capacity. In loess regions traversed by transmission lines, however, systematic research on uplift performance remains limited, often leading to inadequate design, particularly under moistened soil conditions.
