The reclamation of dredging silt to form land areas is a high-quality solution for resource utilization and environmental protection.However，in the construction of land areas formed by reclamation of soft soil，most of the projects are small load storage yards，industrial park roads，and green areas，etc.Taking the foundation treatment project of the reserved storage area behind the 200 000-ton bulk cargo berth of the Qingdao Port Dongjiakou Port area ore terminal project as an example，we expound the design，construction and 6 years after use of the project in detail，and show the evolution of deep hydraulic fill soft soil during the construction and 6 years after use from multiple aspects.We carry out a detailed introduction to the changes in soil moisture content，pore ratio，shear strength and other indicators during different periods，compare settlement calculation and monitoring data during construction，and analyze the height of ore storage under different shear strength indicators during different periods.The results show that it is feasible to use hydraulic fill soft soil to form land areas in high load ore storage yards.Through reasonable foundation treatment methods and orderly increase of storage loads，the ore storage yard can ultimately achieve full load storage.
