摘要
采用三维离散元程序研究了岩体中爆炸波的传播过程。首先 ,通过与弹性解析解的比较 ,验证了该程序的可靠性 ;然后用面面接触模型模拟了爆炸引起的地面振动 ,结果表明离散元法基本上可以客观地描述振动过程的一些性质。
The three-dimensional discrete component process is applied to study the propagation course of explosive wave in rock. The relaibility of the process is vertified after comparing it with the elastic analytical solution, the ground vibration is simulated by contracted blasting , the results reveal that the discrete component method can fundamentally describe the properties of vibration course.
