Experimental Hazardous Rock Block Stability Assessment Based on Vibration Feature Parameters

<div>Structural model of a hazardous rock block and its dynamic analysis model. (a) Structural model. (b) Dynamic model. Here, (a) and (b) are the position coordinates of the rock center of mass (point (W)), (m) and (n) represent the size of the rock, (l) and (d) represent the size of the potential failure plane, (k) is the equivalent stiffness of the potential failure plane, and <i>θ</i> is the microrotation angle under excitation.</div>
