Analysis of the dynamic response of the icecap structure under the action of explosion wave

Aiming at the problem of the icecap structure existing in the ice-jam flood disaster prevention and reduction engineering, considering the action of the explosion wave under the water surface, a new train of thought is introduced in researching how to make the fracture due to dynamical bending in the icecap structure so as to make it destroyed, in which the weak tensile behaviour and the characteristic of being easy to be cracked of the ice structure are utilized. The dynamic character under the action of explosion in the water is adopted in this research, and the model of the icecap plate structure for dynamic analysis is built up for analyzing the dynamic response of the icecap plate structure. In the practical research for ice-breaking engineering, experimental research about explosive ice-jam flood disaster prevention and reduction was processed, which may provide credible data information for the further theoretical research.
