Filling body-rock interface device and method based on DIC and acoustic emission monitoring

The invention provides a filling body-rock interface device and method based on DIC and acoustic emission monitoring, and belongs to the technical field of interaction of filling bodies and surrounding rocks. The device comprises a test platform, a horizontal counter-force frame, a vertical counter-force frame, a horizontal loading device, a vertical loading device, a shear box, a shear force load sensor, a vertical pressure load sensor, a horizontal displacement sensor, a vertical displacement sensor and the like. According to the invention, mechanical parameters and strain field distribution of the filling body-rock interface and acoustic emission characteristics in the shear failure process can be researched, the aims of visualization and quantification of the shear degradation process of the filling body-rock interface are achieved, and the problems that the existing direct shear apparatus is invisible, blind in shear and single in test result are solved. 本发明提供一种基于DIC及声发射监测的充填体-岩石界面装置及方法，属于充填体与围岩相互作用技术领域，
