超声地震模型必须遵循一定的相似准则才能得到符合要求的模拟结果。通过相似变换将模型构造模拟天然的地质构造。实际工作中只要能满足研究所需的主要物理特征即可。本文结合北京地区地震模型实验,着重介绍了波动方程的不变性、波速、尺度及震源振动方式等几个关键问题的相似性准则方面的考虑,供读者参考。 Ultrasound seismic models must follow certain similarity criteria to obtain satisfactory simulation results. The model is constructed to simulate natural geological formations by similar transformations. As long as the actual work can meet the research needs of the main physical characteristics can be. Based on the seismic model experiment in Beijing area, this paper focuses on the consideration of the similarity criterion of several key issues such as the invariance of wave equation, wave velocity, scale and source vibration mode.
