| 摘 要： | 运用LS-DYNA3D程序对封闭岩体中的爆炸过程进行了数值模拟,研究表明,利用LS-DYNA3D 程序模拟得出的质点振动速度峰值与理论公式计算出的结果基本相符;另外,模拟得出的随时间变化的地震动加速度可作为地面结构响应计算时的激励,这克服了爆炸地震波激励难以确定的困难,为爆炸地震波对地面结构的影响效应研究及计算方法提供了一定的参考.

| Abstract: | Using the LS-DYNA3D software, the numerical simulation is realized, which displays objectively the explosion process in rock. The research shows that the simulative result of node maximal vibration speed accords with theoretical consequence. In addition, the simulative seismic acceleration can be used to calculate the response of ground structure. It solves the problem that blasting seismic waves is not easy to ascertain. It is advantageous for studying the effect of blasting stress waves on the ground structure and calculating method. |
