Sliding Criterion (geotechnical Engineering)
The sliding criterion (discontinuity) is a tool to estimate easily the Shear strength (Discontinuity), shear strength properties of a Discontinuity (Geotechnical engineering), discontinuity in a Rock (geology), rock mass based on visual and tactile (i.e. by feeling) characterization of the Discontinuity (Geotechnical engineering), discontinuity. The shear strength of a discontinuity is important in, for example, tunnel, Foundation (engineering), foundation, or Slope stability analysis, slope engineering, but also stability of Slope stability, natural slopes is often governed by the shear strength along discontinuities. The ''sliding-angle'' is based on the ease with which a block of rock material can move over a discontinuity and hence is comparable to the ''tilt-angle'' as determined with the Tilt test (Geotechnical engineering), ''tilt test'', but on a larger scale. The ''sliding criterion'' has been developed for stresses that would occur in slopes between , hence, in the order of ...
