利用FLAC3D数值模拟动态软件中的仿真模块,对实测地震波信号在不同岩质边坡中的传播特性进行模拟,通过控制变量研究,得到震动波在岩质边坡传播中的阻尼效应及反射规律等结论。此外,通过监测露天矿采场实际爆破情况,验证了震动波在预裂爆破形成的预裂缝中传播的衰减效应。
The simulation of FLAC3D software is used to simulate the propagation characteristics of the measured seismic signals in different rock slopes. The damping effects and reflection laws of the vibration waves in the rock slope are obtained through the study of control variables in conclusion. In addition, by monitoring the actual blasting conditions in the open pit, the attenuation effect of the shock waves propagating in the pre-fractures formed by the presplitting blasting is verified.
