Fluctuation Characteristic Test of Oblique Stress Waves in Infilled Jointed Rock and Study of the Analytic Method

Table 1

Mechanical parameters of the simulated rock and joint.

Material category	Mortar ratio	Parameter
		Density (g·cm^−3)	Elastic modulus (GPa)	Poisson’s ratio ()
Rock	20 : 40 : 9	2.08	31.3	0.25
Joint	20 : 60 : 11	1.86	26.5	0.32

The proportion of mortar is cement: sand: water: cement is marked with 42.5 cement; fine sand is made of river sand with a particle size of 0.5 mm∼1 mm.
