【Abstract】 The thin-plate modeling technique can reduce production cost and shorten production circle in physical experiments of seismic exploration.By simultaneous performance of the manufacture and observation,this processing and observation method can decompose 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 advantages 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 structures but also help recognize and analyze different kinds of seismic waves during the 3D seismic exploration physical modeling of complex structures.更多还原
