摘要
为了研究地震波在地下的传播规律,实验中,通过动态光弹物理模拟装置直接观察了超声脉冲纵波和横波在光学玻璃样品模型中的传播过程,模拟了地震波在含背斜或断层的均匀介质中的传播过程,分析其波场特征,并与地震波数值模拟的结果进行对比分析,同时将物理模拟与数值模拟两者结合能更好地实现地震波传播特性的可视化研究,在地震波场特征研究中具有重要性。
In order to research the propagation of the subsurface seismic wave, the propagation of the P wave and S wave of the ultrasonic pulse are observed in the optical glass sample model by the dynamic photoelastic physical simulation device in the experiment. The propagation of the seismic wave in homogeneous medium including anticlines or faults is simulated, and their characteristics of the wave field are analyzed. Compared it with the results of seismic wave numerical simulation, the result show that the combination of the physical simulation and the numerical simulation can provide better result, it was important in the visualization study of the seismic wave propagation characteristics.
