Abstract

The training base of emergency seismic rescue troops in China is built to satisfy the practical demands and offer a real training surrounding for seismic rescue troops. And the earthquake training ruin is one of main parts of the base. The process of blasting formation design for the earthquake ruin construction A (slab-column structure) is given in this paper. And the original structural design and the blasting scheme design of A are made. The 3D solid model of the construction A is build and the blasting formation process is simulated by use of ANSYS/LS-DYNA FEA software. By simulation analysis, not only the full process of blasting and collapsing of the structure is previewed, but also the structure collapsing formation is acquired. Furthermore the rationality and feasibility of the original structure design is verified, and some useful instructions for original structure design and blasting formation design are available by the research of blasting simulation.
