of dredging and reclamation project in Kuwait,we analyze the geological sampling and testing result in discharging outlet or formed reclaimed slope underwater,and monitor the dredging material in the whole process.Combining with evaluating the suitability of backfill material for vibro-flotation by pre-CPT,which can provide basis and guidance for dredging operation and subsequent ground treatment,it ensures the quality of hydraulic fill material meet the vibro-flotation’[KG-*3]s requirements,and makes greater economic or rationality for ground treatment.The introduced monitoring methods and measurements for dredging material can provide meaningful reference for similar overseas projects.
