Abstract

Abstract

To evaluate the work capability of the aluminum fiber explosive, the field test of explosion cavity expansion in soil by aluminum fiber explosive was performed, and the numerical simulation analysis using the software of ANSYS/LS-DYNA was carried out for further investigation. The relationship between the radius of the explosion cavity and the explosive charge was obtained. Our results reveal that both of the two methods provide a fairly good characterization of the law of expansion during the explosion cavity process in soil of aluminum fiber explosive, and the characteristics the aluminum fiber explosive exhibit are better than those of the emulsion explosive in modelling and work ability, which offers a promising application when used in complicated environments and provides a reference for similar engineering projects.
