Abstract Based on the development of the unique structure of fish head boundin,the shapes of boundinage can be classified into A,B,C,D and E types.The authors modeled B and C types of fish head boundin in physical laboratory,studied the relationship between the length of fish head and the original thickness of layer,and put forward a new method to resume the original thickness of layer by use of fish head boundin.Through the experiment,we obtained the coefficients k1 and k2 for Type B and Type C respectively to resume the original thickness of deformed stratum.
