Abstract
According to the characteristics of the Yellow River ice flood, the author using LS-DYNA numerical simulation and shaped charge technology to research the 20cm thick ice failure characteristics when a certain amount of TNT exploded underwater, analysis the result and get the best explosive blasting point, and compared the numerical simulation results with experimental results, to verify the reliability of the numerical simulation, the results may guide the research of the ice-breaking equipment that based on shaped charge technology.
