Slope Stability Analysis of Stacker–Reclaimer Embankment Under the Influence of Adjacent Stockpile
The present Case study emphasis on slope stability analysis of the Stacker–Reclaimer (S-R) embankment due to an adjacent iron ore stockpile of 20 m height for the site situated in South East Asia. Available Geotechnical Investigation data suggest that subsoil profile mainly consists of weak soft soil in form of silty clay to soft clay up to 15–18 m from the natural ground surface. For slope stability requirement of the proposed embankment for Stacker–Reclaimer foundation, a factor of safety (FOS) was calculated without considering the influence of adjacent stockpile and was observed satisfactory. However, calculating global FOS with considering the influence of adjacent stockpile operation, stability requirement was not within the limit as deep-seated slope failure is observed under the action of iron ore stockpile load. In order to maintain the recommended factor of safety for interacting foundations, various ground improvement techniques were explored. Vibro Replacement stone columns were adopted as suitable ground improvement measures. Sequential filling of stockpile in stages was adopted for monitoring variation in the factor of safety. The global factor of safety at each stage is calculated considering both the improved and unimproved ground conditions. The present paper highlights the geotechnical interaction of adjacent facilities and explores the way forward to address them in design.
