A scattered pile and strong net foundation leveling system for steeled storage tank foundations comprises a plurality of pile foundations and soft cushion platforms and is installed in a roundness area of a soft soil foundation field; the area is divided into a supporting area outside a ring and a reinforced area inside the ring; the pile foundations are thick and short; the pile foundations are divided into supporting piles and reinforced piles; the tops of the pile foundations are provided with large and thick rigid pile covers; the supporting piles and the reinforced piles are respectively and wholly planted into soft foundations of the supporting area outside the ring and the reinforced area inside the ring uniformly; the pile distance is large and accordingly scattered piles are formed; the top surfaces of the pile covers are align to each other; the soft cushion platforms are multiple strong net and scatter stone composite cushion layers; the lower surfaces of the multiple strong net and scatter stone composite cushion layers, the top faces of the pile covers and the foundation soil faces between the multiple strong net and scatter stone composite cushion layers and the top faces of the pile covers are connected in a sliding mode to cover on the area; and storage tank foundation surrounding walls and the steeled storage tanks are constructed on the upper surfaces of the soft cushion platforms. The scattered pile and strong net foundation leveling system for the steeled storage tank foundations has the advantages of being applicable to install in the soft soil foundations, being capable of achieving differential sedimentation control and foundation leveling of the steeled storage tank foundations and being thick and short in pile foundations, few in pile foundation numbers, small in construction difficulty, short in construction period, low in construction cost and good in shock resistance performance.
