The primary objective of the current study is to shed light on specific instances of failures or inadequate performance of geosynthetic-reinforced MSE walls situated in the state of Kerala, India. The research also puts forth potential remedial actions and precautions. It is noteworthy that a majority of these failures of geosynthetic-reinforced MSE walls in Kerala occurred either during or following the monsoon season. The primary factors contributing to these failures were identified as the utilization of locally available marginal lateritic soils in the backfill, insufficient management of external and internal drainage systems, suboptimal filter and drain designs, inadequate compaction of foundation soil, and the lack of necessary ground improvement measures prior to commencing MSE wall construction. The corrective measures proposed include structural repairs involving compaction grouting and soil nailing, reconstruction, and the implementation of stone columns, among others. To mitigate the ingress of rainwater into low-permeability backfill material, preventive measures are suggested for both during and after construction. Rainfall infiltration has been linked to undesirable deformations and bulging in MSE walls. During construction, the backfill can be covered at the end of each workday, and post-construction, a geomembrane layer can be employed to seal the surface. Additionally, a reduction in interface shear strength resulting from the loss of suction due to rain-induced wetting should be considered when utilizing marginal lateritic soil as the backfill for MSE walls. Furthermore, the study found that stone columns effectively enhance the bearing capacity and drainage of compressible clay foundations beneath MSE walls. The reconstruction of a collapsed MSE wall underscores the significance of thorough site investigation and the adoption of appropriate ground improvement measures when necessary.
