The second method is a split underwater dismantling method, but the method not only has high operation difficulty and long time consumption, but also is difficult to ensure zero residue. The third method is a method for foundation demolition by adopting an air bag auxiliary technology in recent years, namely, an air bag is installed under water through a small floating crane, and meanwhile, the whole foundation structure is pulled out of the sea bottom by depending on a suction pump and the lifting capacity of the floating crane, and then the foundation structure is wet-towed to a shallow water area near the shore to be decomposed in the next step; however, when the air bag is filled with air and floats to the sea surface, the difference between the internal pressure and the external pressure is increased, the air bag has the possibility of bursting, the safety of the air bag is difficult to guarantee, and meanwhile, in order to ensure that the foundation structure is stably pulled up and floats, a set of central control system for intensively controlling the inflation quantity and the pressure of each air bag needs to be researched, so that the safety and the reliability of the air bag auxiliary method need to be further demonstrated.
