摘　　要：在地震勘探物理模型实验中,采用页面物理模型模拟实验技术,可以降低物理模型的制作成本,缩短实验周期。采取加工与观测同步进行的方法,可以分解复杂构造模型的地震波场,有利于研究各类震波在模型中的传播问题。笔者介绍了页面模型的制作和观测技术,讨论了页面模型上波的分布特点,描述了典型构造模型的地震波场。可以发现,页面物理模型的制作和观测简单,制作周期短,成本低;在得到的地震波场图上,各类震波的运动特征明显而清晰;它不仅可以模拟各种简单的地质构造,在开展复杂构造的三维地震勘探物理模型实验时,有利于各类震波的识别与分析。The thin-plate modeling technique can reduce production Cost and shorten production circle in physical experiments of seis- mic exploration. By simultaneous performance of the manufacture and observation, this processing and observation method can decom- pose seismic wave fields and help us know the propagations of various types of seismic waves in complicated media. This paper reports the manufacture and observation technique of the thin-plate model, discusses the characteristics of wave distribution in the thin-plate model, and describes the seismic wave fields of typical structure models. It is found that the thin-plate physical model has the advanta- ges of simple manufacture and observation, short manufacture cycle and low cost; in addition, the movement characteristics of various seismic waves are obvious and distinct in the obtained seismic wave field map. It can not only simulate various simple geological struc- tures but also help recognize and analyze different kinds of seismic waves during the 3D seismic exploration physical modeling of com- plex structures.
