The technical key points are as follows: 1, N relatively static floating islands are built by utilizing seawater buoyancy, the floating islands are synthesized from cheap materials, and bridges are erected on the floating islands; 2, each floating island is formed by uniformly distributing m seabed stainless steel wire ropes on the left side and the right side of the floating island, straightening and firmly holding the seabed stainless steel wire ropes, and the m stainless steel wire ropes are wound and tied on the m reinforced concrete blocks sinking into the seabed respectively; and 3, the absolute horizontal height of the floating island is not changed. The floating island does not freely float on the water surface, and at the lowest tide level, the buoyancy ensures that the m strands of stainless steel wire ropes have moderate tension. And 4, the core principle is as follows: mechanical balance, namely buoyancy F1 = borne bridge gravity G + tensile force F2 of a seafloor stainless steel wire rope.
