This invention discloses an experimental apparatus and method for a similar model of a rock wall expansion. The apparatus includes a transparent experimental chamber, a layered gelatin system, a terrain simulation system, a dynamic injection system, a multimodal monitoring system, and a data acquisition and processing system. By independently adjusting the stiffness and density ratios of the upper and lower gelatin layers, combined with a detachable double-slope terrain mold, a systematic study of the coupled effects of multiple factors such as terrain, stiffness layering, density layering, and injection rate is achieved. The three-dimensional morphological evolution of the rock wall is simultaneously monitored using a multi-view high-speed camera, and the full-field displacement field, strain field, and principal stress direction during the rock wall expansion process are inverted in real time using digital image correlation technology. This reveals the control mechanism of stress gradient reversal caused by terrain on the lateral expansion and cessation of the rock wall. Furthermore, dimensionless analysis and boundary correction improve the similarity between the model and the natural prototype, providing a reliable experimental platform for volcanic eruption prediction and magma transport law research.
