Ultrasonic guided wave nondestructive testing of anchorage quality of rebar resin bolt based on EMD-PCA
Abstract Currently, the ultrasonic guided wave inspection of the anchoring quality of rebar resin bolts in coal mine tunnels faces issues such as rapid signal energy attenuation, waveform superposition of reflected waves, and waveform complexity, making it difficult to effectively identify anchoring...
