Bubble ice breaking method

The invention belongs to the technical field of ocean and inland river ice breaking, and particularly relates to a bubble ice breaking method. A bubble generating device is used for pulsation bubbles at the position, vertically away from an ice layer by D, below the ice layer, D is larger than 0 and smaller than 2R, R is the maximum radius capable of being reached by the bubbles generated by the bubble generating device under the situations that the water depth is the same, and the ice layer does not exist, the near ice layer is damaged through the movement of underwater movable bubbles, and ice breaking is conducted; one or more bubbles are generated in water, the bubbles are expanded and then contracted, and ice layer damage is caused through at least one of the following four forms. According to the bubble ice breaking method, designing and manufacturing of an ice breaker are not needed, throwing of bombs, explosives and the like is not needed, and cost is saved; a mechanical structure does not directly co
