Description

Technical Field

[0001] The present invention relates to the field of structural geology research, and particularly to a tectophysical simulation experimental device for full-angle superposition deformation of compression-tension and shear. Background Technique

[0002] Tectophysical simulation experiment is an important technical means for studying and verifying the mechanism and evolution process of tectonic deformation. Based on the similarity criterion, tectophysical simulation experiments can simulate large-scale and long-term geological tectonic deformation processes under short-time conditions indoors. In recent years, tectophysical simulation experiments have been widely applied in earth science research, energy and mineral exploration and development, and geological disaster warning and prevention, and remarkable results have been achieved in scientific research and production assistance.

[0003] Common basic tectonic types are mainly compression tectonics, pull-apart tectonics, and shear tectonics. However, in actual situations, tectonic deformation mostly has spatio-temporal superposition. After geological bodies experience the superposition of multiple deformation mechanisms in time and space, the current tectonic morphology is formed. In previous single tectophysical simulation experiments, the deformation mechanism was relatively single, and it was impossible to complete the superposition simulation of multiple deformation mechanisms, making it difficult to meet the research needs of complex superposed structures.
