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.

The method dynamically updates the liquid level in each compartment, the mass of water entering the compartment, its center of mass, and the change in moment of inertia of the bridge sections caused by water ingress, based on the size and location of the breach. After determining the position and inclination angle of each bridge section in a stable equilibrium state in still water, the method calculates the generalized added mass coefficient, radiation damping coefficient, and wave excitation force of the floating bridge system under water ingress conditions based on potential flow theory. Finally, it uses the multi-body time-domain hydrodynamic analysis equations to analyze the dynamic response of the damaged floating bridge under load. This invention constructs a theoretical framework for the dynamic response analysis of a damaged floating bridge in still water using multi-body dynamics methods, constructs a multi-section, multi-compartment water ingress model using the modified Bernoulli equation, and then uses potential flow theory to conduct time-domain hydrodynamic analysis, achieving efficient dynamic response prediction and improving calculation accuracy and efficiency.
