To accurately classify the stability of surrounding rock masses, a novel method (VSV-BDA) based on virtual state variables (VSVs) and Bayesian discriminant analysis (BDA) is proposed. The factors influencing stability are mapped by an artificial neur

Three-point-bending tests on notched concrete beams were performed with real-time AE (acoustic emission) monitoring. Based on the nearest neighbor theory modified from seismology, the minimum interevent distance ηj* for every AE event is calculated.

Shear-related joint deformation is critical in the study of the anisotropic characteristics of a single rough joint in the ground stress field, such as aperture development within rock mass joints under the disturbance of mining construction, hydraul

By combining the b-value and acoustic emission (AE) event density, a parameter referred to as the T value was developed to construct a fracture process zone (FPZ) using AE data to study the fracture process of mortar and concrete beams under three-po
