Abstract:
Start typing the abstract here. The increased surcharge on existing retaining walls,
resulting from new infrastructure or pavement construction, heightens lateral pressure
and may destabilize the retaining wall. Researchers explored various techniques like
relief shelves, EPS geofoam, and soil reinforcement to address high lateral earth
pressure, but found them impractical for existing retaining walls. This study aims to
evaluate the feasibility and effectiveness of vertical plate anchors for stabilizing
existing cantilever retaining walls. In this study, Redistribution of lateral earth pressure
of existing cantilever retaining wall with and without vertical plate anchors has been
evaluated using FEM on Plaxis 2D. In the parametric analysis, different models were
examined to explore the impact of geometrical and soil strength parameters on the
Factor of Safety (FOS) of the cantilever retaining wall. Based on the findings of this
study, the use of a vertical plate anchor can significantly enhance the stability of the
wall. The FEM model's validation involves comparing lateral earth pressure values
obtained from PLAXIS program with the analytical equations. Non-linear regression
analysis using a polynomial regression model was performed to predict the Factor of
Safety (FOS). The predicted FOS values showed a high level of accuracy when
compared to those determined by Plaxis 2D.
