The quartz-mica schist is a typical schistosity rock and its structural features are distinct from stratified or layered rocks. Its specific property leads to different deformation and failure mechanism between the quartz-mica schist and stratified or layered rock. Because the quartz-mica schist is easy to disintegrate in water and the angle of schistosity plane can change significantly

it is difficult to systematically carry out the mechanical test of the rock samples with different angles due to sampling difficulties and rock variability. As a research method commonly used in the field or rock mechanics

physical simulation method conducted on similar materials is frequently used to qualitatively explore the mechanical properties and behavior of rocks. The structure and tectonic characteristics of the quartz-mica schist were revealed by electron microscopy and polarized light microscopy

and the deformation and failure mechanism was analyzed from macroscopic and microscopic perspectives according to the experimental result. The device and method for making materials similar to schistosity rock were developed

and the corresponding physical simulation material was obtained. The mechanical behavior

failure characteristics

and mechanical parameters of the similar material were studied by means of uniaxial and triaxial tests. Based on the apparent analysis of material structure and the results of mechanical tests

the reliability of the device

the feasibility of the proposed method

and the similarity of the material itself were verified.
