Question Regarding PLAXIS Analysis

• Large-scale slope stability check is acceptable: This means your global factor of safety (FOS) is within acceptable limits.

• Displacement at the heel of the retaining wall: It usually arises due to localized stress concentration, soil-structure interaction, or minor plasticity zones in the backfill.

• Should it be a concern? If displacements are within the elastic limit and do not exceed design tolerances, its generally acceptable. However, if the displacements grow over time or are significant, additional reinforcement (e.g., tiebacks, ground anchors) should be considered.
