Method for manufacturing intermittent weak interlayer structural plane

A method for manufacturing an intermittent weak intercalated layer structural plane comprises the following steps that 1, an engineering site is surveyed, and the size and mineral components of a weak intercalated layer area influencing rock stability are ascertained; step 2, making an experimental scheme according to the size and mineral composition of the weak intercalated layer area, making a strip-shaped intermittent weak intercalated layer structural plane consistent with engineering, and obtaining various indexes of mechanical properties of the weak intercalated layer structural plane through a direct shear test; step 3, installing an intermittent weak intercalated structure surface manufacturing device in a laboratory; step 4, according to the experimental scheme, prefabricating a required weak intercalated layer by using a weak intercalated layer system; 5, after the weak interlayer in the weak interlayer system is pushed to the fixing system, the connecting clamp is loosened to enable the replacement
