摘要

Explosive lining is simplified as an axisymmetric problem. Using DYNA-2D commercial program, the displacements variation of mortar with time during the explosive lining is analyzed by numerical simulation. The numerical simulation results meet the on-site experiment results. Research indicates that fluid mortar could be pressured into a stable lining structure through explosive lining. Free face is one of the important factors influencing shape of the lined shell.
