Abstract：In order to study the fracture process of ice layer under vertical load and its influencing factors, the explicit dynamics analysis software LS-DYNA is used to carry out the numerical simulation of interaction of ice layer and rigid cylinder based on penalty function contact algorithm. The fracture process and phenomenon of ice layer under different vertical load, relative velocity, contact angle, as well as contact area between cylinder and ice layer are analyzed. The results show that: when the maximum tensile stress is greater than the tensile strength of ice, the ice layer under the vertical load will generate radial cracks and circumferential cracks one after another, and the breaking load of radial cracks is less than that of the final ice layer；the ice layer under the concentrated load is more likely to occur than that under the uniform load；When there is a contact angle between cylinder and ice layer, the failure mode of the ice layer changes significantly.
