Industrial CT scanning is utilized to obtain CT tomographic images; a nanoindentation tester is employed to acquire micrographs and indentation load-displacement curves; low-speed binocular cameras, universal testing machines, and high-speed cameras are used to collect binocular images, load-displacement curves, and monocular images respectively. To meet the multi-dimensional characterization requirements of simulated lunar soil bricks, a full-process technical framework of "microstructure analysis - mesomechanical characterization - macroscopic performance prediction" was constructed. Additionally, a digital twin model was established to non-destructively predict the macro-micro structural changes and mechanical properties of simulated lunar soil bricks. Finally, a large-scale dataset for intelligent characterization of multi-scale structure-mechanical performance of simulated lunar soil bricks was developed.
