Experimental and numerical simulation assessment of fracture evolution and tensile strength recovery in Grout-reinforced fractured surrounding rocks

|
By Oladoyin Kolawole, Olufemi Olorode, Matthew O. Sonibare
| Nature Verified
Abstract The surrounding rock around deep underground excavations generally contains fractures and joints that significantly reduce mechanical integrity, particularly in zones where excavation-induced unloading, stress rotation, and anisotropic deformation generate tensile stress concentrations. These tensile regimes govern crack initiation, fracture propagation, spalling, and progressive instability around tunnels, caverns, mines, and wellbores.
