A portable, visual, and quantifiable teaching and research demonstration platform for rock fractures, suitable for classroom experiments, scientific research comparisons, and enterprise training scenarios in geology, mining, civil engineering, and petroleum engineering majors in universities. The teaching scenario includes slope stability experiments: students adjust the orientation of cracks on site, observe the formation of sliding surfaces and the reinforcement effect; Tunnel surrounding rock classification: automatically calculate rock mass quality indicators through crack density and RQD; Visualization of hydraulic fracturing: Real time visualization of high-pressure water spreading along fractures and forming a network of fractures; Linkage with numerical software: Experimental data is directly imported into FLAC3D/3DEC or Rocscience series software to complete the "experiment numerical" closed loop.
