Experimental investigation on the spallation characteristics of mudstone under biaxial compressive stress

Mudrock spallation has critical implications for tunneling rock control. Spallation experiments of mudstone under biaxial compression were conducted with mitigated end friction. The results showed that the stress–strain curve of mudstone under biaxial compression displayed a significant strain rebou...
