Experimental Study of Single Structure Surface Dangerous Rock Mass Dynamic Characteristics Based on Constant Micromotion

Table 2

Model material properties.

Material properties	Cantilever dangerous rock mass model	Sliding dangerous rock mass model
Density (kg·m^−3)	2230	2502
Elastic modulus (GPa)	2.4	3.01
Poisson ratio	0.28	0.30
Tensile strength (MPa)	0.0975	—
Cohesion (MPa)	0.926	—

Note. Due to the change in time and operators in the two experimental model castings, the physical properties of the model materials were different.
