More and more researchers are focusing on the service condition of operational tunnel structures. In sulfate strata, tunnel lining structures are frequently affected by sulfate erosion, resulting in structural damage. However, the fracture evolution law and destabilization damage precursors of lining structures after erosion are not clear at present. Therefore, this study aimed to analyze the failure precursors of concrete subjected to sulfate erosion by testing the uniaxial compressive strength and acoustic emission (AE) phenomenon of the specimens. The b -value in the G -R law was utilized t...
