英文摘要This paper reports the relationship between electrical resistivity and rock failure during uniaxial compression. Experiments of rock samples on an electro-hydraulic servo-controlled testing machine show that the variation of electrical resistivity is closely related to rock deformation. Near to rock fracture, microcracks appear and change the microstructure of rock mass, causing the rupture of mineral crystal lattice, and the electrical resistivity has a rapid variation with the growth of cracks. The experimental result shows that rapid variation of electrical resistivity occurs at the critical point with stress level of approximately 75-85 % relative to the peak strength in uniaxial compression. This research may be useful to indirectly detecting the critical point of rock fracture.
