[0002] With global warming and the melting of ice caps, the opening of polar routes and resource exploration have become possible, but the existence of sea ice makes polar operations too difficult. At present, the research on the mechanical deformation mechanism and interaction force of ice is not mature, and a complete, efficient and feasible polar ice breaking technology system has not been formed. The current main ice breaking methods include blasting, mechanical breaking and ice breaking ship collision, but these methods have certain limitations such as environmental pollution and low efficiency.

[0003] Water jet technology is mainly used in the fields of mine exploitation and tunnel construction. It cuts and breaks rocks by high-pressure jetting fluid. Compared with traditional blasting and mechanical breaking methods, water jet rock breaking technology has the advantages of small environmental impact, precise control and high work efficiency. In the polar marine environment, the huge impact force generated by high-speed water jet can cause ideal and controllable damage to large ice bodies, and the water for jetting can be replenished at any time. Therefore, water jet technology can be applied to the field of ice breaking as a new method, and a set of experimental device for jet breaking ice under submerged and non-submerged working conditions is needed to adjust different experimental parameters, so as to facilitate the research on the water jet breaking mode and damage mechanism.
