摘要
爆破漏斗是爆破破坏的基本形式。利用Ls-dyna软件,模拟了条形药包和集中药包起爆时爆破漏斗的形成过程和形态,对模拟结果进行了分析,计算结果表明:靠近炸药部位的岩石是由于压缩破坏,岩体表面属于拉伸破坏,压缩破坏区和拉伸破坏区存在较明显的分界线。
Blasting crater is the basic form of the blasting damage. The Ls-dyna software was employed to simu- late the blasting crater forming process and shape when linear charge and concentrated charge are ignited respectively,the simulation results are analyzed and the results show that the part of rock mass near charge is fragmentized because of compression and the part of rock mass near free surface is fragmentized because of tension, there is an obvious boundary between compression fragment zone and tension fragment zone.
