Abstract

This paper, based on an ongoing mountainous area high-fill embankment project, investigates the high-fill pile foundation and cantilever retaining wall composite support structure in loess gully regions. A numerical simulation method was employed to analyze the stress and deformation process of the composite support structure, revealing the characteristics of stress distribution and deformation patterns of the structure. The main research conclusions are as follows: under the action of earth pressure, significant stress concentration occurs at X = 0.7m and X = 5m along the X-direction of the bottom slab of the retaining wall. The cantilever retaining wall exhibits a tendency to tilt towards the fill side, with horizontal displacement and settlement showing a stratified distribution feature. Meanwhile, the contour line displacements are equal at the connection between the retaining wall and the pile foundation, indicating that the composite structure deforms coordinately under earth pressure as a whole.
