First of all, ice flood will undoubtedly bring floods. Ice flood is usually divided into two periods, freezing period and river opening period. The flood disaster caused by ice jam usually occurs during the freezing period. Flood disasters caused by ice dams usually occur during the river opening period. The water that cannot normally flow downstream due to the ice dam rises to the upstream, and the water level soars. If there are no measures to break the ice, the rising water level will cause the ice dam to burst, which will lead to floods.

Secondly, the ice pressure of ice flood will also cause disasters. Ice pressure refers to the force that ice acts on buildings. Including the dynamic pressure caused by the impact of flowing ice, the static pressure transmitted to buildings by the action of wind and water in a large area of ice, and the static pressure caused by the expansion of the whole ice sheet.
