Global Stability Analysis of Column-Supported Embankments
Publication: Geo-Congress 2024
ABSTRACT
Global stability evaluation is an important component of the overall design of column-supported embankments (CSEs). This paper presents two CSE cross sections that are analyzed using limit equilibrium (LE) procedures that are adapted to account for vertical load transfer to the columns by either modifying unit weights or stresses within the model. The CSE cross sections are also analyzed using the strength reduction factor (SRF) method, and the two methods are compared. The results of the study suggest that the effects of complex shearing that can be modeled by SRF analysis, but not LE analysis, are more significant than the effects of vertical load transfer.
