Abstract

As an innovative retaining structure, the pile-supported beam retaining wall has gained extensive application in complex geological environments such as submerged embankments, steep slopes, and low-bearing-capacity embankments due to its unique design philosophy and constructional merits. This study investigates its performance in steep high-fill embankments within mountainous highway projects through integrated case-study analysis. By conducting multi-criteria scheme evaluations, the research highlights the structural superiority of pile-cap retaining walls in such contexts. The design framework of pile-cap systems not only addresses insufficient subgrade bearing capacity but also delivers dual functionality as slope-stabilizing supports, significantly enhancing overall embankment stability. The findings, corroborated by field monitoring data and elastoplastic finite-element modeling, validate its field efficacy in complex geological settings. This work establishes critical theoretical frameworks and practical protocols for stabilizing steep-slope embankments, offering transformative insights for geotechnical engineering.
