A series of experiments concerning the interactions between a spark bubble and an ice floe with a hole were done. The principal focus were the dynamic responses of the ice floe, including crack growth and development, under the combined loads of bubble and free surface, involving initial shock waves, jet impact, secondary shock waves and water spike. The entire evolution of the ice specimens under these processes (bubble and free surface) were recorded simultaneously by two high-speed cameras from birds-eye and side views. An intact ice floe with the same parameters was chosen as a benchmark. The influence of dimensionless parameters was investigated, including bubble-ice distance γ, radius of hole λ and ice thickness τ. Three types of ice-breaking patterns were summarized versus combined parameters (γ, λ, τ). Among them, a unique pattern was found for the ice floe with a hole, which was just first damage on the ice floe with radial cracks but no secondary damage. This damage pattern only happened when the bubble bursts at the free surface in the ice hole for very small γ and τ (at least γ + 0.9τ < 1). Once the bursting happened, the energy of a high-pressure bubble released in advance and no secondary shock wave and damage on ice was observed. This was a unique phenomenon for the ice floe with a hole.

进行了一系列有关火花和带孔浮冰之间相互作用的实验。主要焦点是浮冰在气泡和自由表面的组合载荷下的动态响应，包括裂纹的增长和发展，涉及初始冲击波，射流冲击，二次冲击波和水刺。在两个过程中，用两个高速摄像头从鸟瞰和侧面同时记录了冰标本在这些过程（气泡和自由表面）下的整个演变过程。选择具有相同参数的完整浮冰作为基准。研究了无量纲参数的影响，包括气泡冰距离γ，孔半径λ和冰厚度τ。。总结了三种破冰模式与组合参数（γ，λ，τ）的关系。其中，对于带孔的浮冰，发现了一种独特的模式，这只是对具有径向裂纹的浮冰的第一次破坏，而没有二次破坏。这种损害图案仅发生了，当在冰空穴的自由表面的泡沫破裂对于非常小的γ和τ（至少γ  +  0.9 τ  <  1）。一旦破裂发生，高压气泡的能量就会提前释放，并且没有观察到二次冲击波和冰上的损坏。对于带孔的浮冰来说，这是一种独特的现象。
