What is a Split Face Block?

Cooperating with the slip surface, it can cut the rock body and separate it from the parent rock to form various steep dip geological structural surfaces of the slip body. When the direction of the cutting surface is almost parallel to the direction of the engineering force, it is called a longitudinal cutting surface; when the direction of the cutting surface is almost perpendicular to the engineering force, it is called a transverse cutting surface. When the structural surface has a certain strength, the longitudinal cutting surface can generate sliding resistance, the transverse cutting surface generates tensile strength, and the anti-sliding stability is very favorable. ^[1]
