This document discusses a study on the impact of changes in geotechnical properties of lateritic soil on the serviceability of cantilever retaining structures over time. The study focuses on a retaining structure constructed in Dasgaon village, Maharashtra, India in 2017. Key findings from comparing original design parameters to current soil properties include: 1) properties like density, shear strength, and permeability that impact structural safety have changed, 2) this has likely decreased the factor of safety below design thresholds and reduced the structure's serviceability. The authors conclude geotechnical properties should be re-evaluated periodically to ensure retaining structures can withstand their intended design lifespan.
