APPLICATION OF SIMULAION EXPERIMENT TO THE STUDY OF STRUCTURAL EVOLUTION—AN EXAMPLE OF THE ZHUANGXI BURIED HILL

Structure simulation experiment is one of important parts in the study of structures.It has gained many important results in the past decades,but many questions are remained for the research of fold.So it is important to find some means to realize fold simulation.Zhuangxi buried hill is a typical fold in Jiyang depression.On basis of clear understanding of the formation boundary condition and lithological sequences of Zhuangxi buried hill,the experiment materials are elaborately selected.According to similarity criteria,formation of Zhuangxi buried hill was simulated in a designed physical model.After four phases experiments,the result is coincided with the theory analysis and some propositions for structural evolution of complicated buried hill are proved.It provided a good example for fold physical simulation.
