Creep Investigation on Shale-Like Material with Preexisting Fissure under Coupling Temperatures and Confining Pressures

Table 1

Comparison table of parameters between shale-like material and Tang Kou shale.

Mechanical parameters	Density (g/cm^3)	Young’s modulus (GPa)	Compressive strength (MPa)	Internal friction angle (°)	Cohesion force (MPa)
Parameters of Tang Kou shale	1.8∼2.0	1.3∼2.1	10∼20	45∼65	3∼20
Parameters of shale-like material^a	1.902	1.864	12.077	32.751	4.199

^aParameters of shale-like material are the average value from intact shale-like material’s testing results.
