摘　　要：采用一维球对称流体弹塑性模型模拟了一系列TNT填实爆炸引起的周围岩石动力学参量的变化 ,根据计算结果拟合了岩石中峰值应力、粒子速度、加速度及位移的近似公式 ,并与一些文献中提供的实测结果进行了比较 ,说明数值模拟可为爆破工程。The stress produced by a series of chemical explosions were numerically simulated with one dimension spherical symmetric elastic\|plastic flow model. The acceleration, velocity, stress and displacement of particle in rock were calculated and the approximate agreement was observed between calculated value and experimental data. [
