中文摘要：
通过与相关文献的实验结果对比，验证了数值模拟爆炸波在岩石介质中传播的可行性．借助于显式非线性动力分析有限元程序LS—DYNA，数值分析了爆炸波传播后岩石中损伤演化和能量耗散特性．数值计算结果表明，在爆炸荷栽作用下，岩石可分为3个区：与炸药相邻D为1的破碎区，0〈D〈1的损伤区，D近似为0的弹性区，得出各区的范围；爆炸波输入岩石的大部分能量用于破碎岩石，弹性波携带能量占很少一部分；岩杆中能量密度峰值随距离以指数形式衰减．
英文摘要：
Compared with experimental results from references, the feasibility of the numerical simulation of blast wave diffusing in rock was proved. On the basis of numerical program LS-DYNA, damage evolution and property of energy dissipation in rock were analyzed after diffusion of blast wave. The numerical results show that under blast loading, there exist three zones in rock： crushed zone near the explosive （D=I）, damaged zone （0〈D〈1） and elastic zone （D≈0）. The range of each zone was obtained. Most input energy of explosive waves is consumed to crush rock. The energy of elastic wave occupies only a fraction. The peak value of energy density of rock attenuates exponentially with distance.
