Solution: – As the embankment was constructed on weak soil and had already failed, it was understood to go for detailed geotechnical investigation and provided suitable ground improvement technique based on the report. We proposed ground improvement with PVDs and geotextiles – with detailed calculations, plan & section drawings and stage wise construction sequence with estimated settlement and SBC checks. The solution was scrutinized by IIT and accepted / approved. The ground improvement was executed on site as per approved scheme along with proposed instrumentations and had performed successfully for the intended purpose with satisfactory results. Therefore, it can be said that, for locations with very weak soft clay for higher depths, PVDs can be feasible and effective solution to reducing time required for consolidation and accelerate the settlement.
