运用多刚体系统动力学及接触冲击理论建立了节理岩体弹塑性动态本构模型。基于DYNA－2D程序原理及其框架，利用所建模型，模拟了节理岩体的爆破过程，量化了节理岩体在爆炸载荷作用下不同时刻的应力场。
The elastic-plastic dynamic constitutive model of jointed rock mass is established by multi-body system dynamics and contact impact theory. Based on the principle of DYNA-2D program and its framework, the model was used to simulate the blasting process of jointed rock mass and quantify the stress field of jointed rock mass under different blast loads.
