Tectonic Physical Simulation Experiments: Evolution from Qualitative Exploration to Quantitative Analysis and Future Prospects

This review synthesizes the historical development, research methodologies, and current scientific issues of tectonic physical simulation experiments, while also looking forward to future research directions in the field. Since the early 19th century when James Hall first simulated fold formation, the field has undergone a transition from qualitative studies to quantitative analysis. We analyze key research and technological advancements across the early exploration, mid-term development, and late maturation stages, with a particular focus on the introduction and application of the similarity principles, as well as the incorporation of Particle Image Velocimetry (PIV) technology. Despite significant progress, challenges remain in the selection of experimental materials, precise application of similarity principles, and experimental precision. Future research should explore new materials, interdisciplinary collaboration, and the application of big data technology to enhance the accuracy and reliability of simulation experiments.
