摘　　要：根据发育程度,将鱼嘴构造划分成A、B、C、D、E五种基本类型,研究了鱼嘴构造的形态特点以及鱼嘴的周缘长度与岩层初始厚度之间的关系,利用物理模拟的手段,模拟出B、C两种类型的鱼嘴构造,相应地得出了利用这两类鱼嘴构造恢复岩层初始厚度的系数k1、k2,并成功地运用于实际岩石能干层初始厚度恢复.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.
