| 摘 要： | 地下球形药包爆轰后将产生很强的地震波．其传播受多种因素的影响。本文把岩石介质的弹塑性帽盖模型耦合到有限差分法程序中，对一维爆轰波在非均质岩石体中的传播、演化机理进行了数值模拟与分析。着重探讨一维应力波从“硬”岩石层进入“软”岩石层、从“软”岩石层进入“硬”岩石层时，波在形状和强度等方面的变化规律。同时也探讨了岩石介质中存在的“软弱夹层”对一维应力波传播的影响。这些对于人防工程等中的波阻抗的功能梯度效应和智能防护等方面的研究具有一定的参考价值。 |
| 关 键 词： | 岩石介质 一维应力波 帽盖模型 传播与演化 |

| Abstract: | Violent seismic waves will be produced when an underground spherically packed explosive is blasted, and their propagated model is affected by many factors. Based on finite difference methods coupled with the famous elastic-plastic cap model of rock, we did numerical simulation and analysis for the propagation and evolution mechanism of 1-D detonation. The emphasis was put on the waves propagated from hard rock into soft rock, or from soft rock into hard rock. At the same time, the influences of weak intercalated bed between rock mass on 1-D stress-waves are also discussed. All those can be reference for the studies on the function gradient materials of wave impedance and the intelligent defense in civil air-defense engineering. |
| Keywords: | rock medium 1-D stress-waves cap model propagation and evolution |
