According to various characteristics of ice-jam disasters on Yel ow-River, a number of ice-jam removal experiments were carried out using military technologies. The techniques of artil ery bomb penetrating ice sheet, gathering energy perforation bomb breaking ice-jam, and explosive belt dragged by rocket breaking big ice are also studied using ANSYS/LS-DYNA, a finite-element simulation model. The process of ice-jam removal, application conditions and parameters were analyzed. The results can provide theory and technical reference for emergency ice-jam removal in river courses.
