Rock Failure and Instability from a Structural Perspective: Insights from the Shape Effect

The failure and instability of a kind of specific rock structural bodies, such as the spalling-induced thin rock plates and the slender rock pillars, are the key inducing factors of rock engineering disasters and they are closely related to the shape effect, i.e., the height-to-width (H/W) ratio. For application in engineering practice, the strength characteristics and failure modes of the rock structural bodies when their H/W ratios vary in a...
