摘要
为研究震动波在岩质边坡中的传播规律,采用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进行模拟,实时监测并记录坡体不同部位振动响应值,推出震动波在不同岩质边坡中的变化趋势.研究结果表明:揭示了震动波在岩质边坡传播中有阻尼效应,并在接近自由面时可形成反射波等规律.此外,通过对比监测露天矿采场实际爆破情况,为预裂爆破的优化提供了理论依据.
To study the propagation rule of shock wave in rock slope, this paper utilized FLAC3D numerical simulation, the dynamic simulation module of software for the observed seismic signals on different rock side slope, to simulate the propagation of real-time monitor and record the different parts of slope body vibration response value of shock waves in the different change trend of rock slope. Research reveals that the shock wave propagation in rock slope in damping effect, which can form when close to the free surface reflection law, etc. In addition, by comparing and monitoring the situation of blasting open-pit mine stope, this study provides a theoretical basis for presplit blasting optimization.
