★The foundation pit is 38 meters deep; the foundation is a pile raft foundation, with a total of 896 engineering piles, and the raft is 6.5m thickest.
★The underground uses giant columns + steel plate concrete shear walls + pure reinforced concrete frame structure, with a plane size of 136x84m.
★The main tower is a tube-in-tube structure, and the inner and outer tubes together form a multi-layer fortified lateral force-resistant structural system.
★The outer frame tube is composed of giant columns, support conversion trusses and sub-structures.
★The core tube adopts a concrete shear wall structure containing steel frames (plates).
