摘要

国家地震紧急救援基地是为了满足实战要求，为地震救援人员提供一个真实的救援训练环境而建立的。其中地震训练废墟是国家地震紧急救援训练基地的核心内容之一。本文给出了地震废墟构筑物A段（板柱结构）的爆炸成型设计流程，对废墟A段进行了原型结构设计和爆炸方案设计。采用ANSYS/LS-DYNA有限元软件建立了该结构的三维有限元实体模型，对其爆炸成型过程进行了仿真分析。通过模拟仿真研究预演了结构爆炸倒塌全过程，得到结构的倒塌型态；并通过爆炸倒塌模拟研究，对原型结构设计的合理性和可行性进行了验证，并对原型结构设计和爆炸成型设计提供了有益的指导。

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.
