Rock Joint Coefficients Derived from the Three-Dimensional Fourier Reliefs

Popis výsledku v původním jazyce

Coefficients of rock joints serve in geotechnical practice for determining shear strength of rock masses. Evaluation of the stability of rocky terrains containing joints is important from the viewpoint of safety. Larger surface irregularities of joints contribute to a better mechanical stability of rock masses. One of the possible ways of evaluating joint rock coefficients is based on the numerical assessment of surface morphology. The comparison of morphologies between the relief of the investigated rock joint and the reliefs of standard specimens whose coefficients are known enables to assign a proper coefficient to the investigated joint. The Fourier digital reliefs are useful auxiliary tools for such a comparative technique. The technique is however accompanied by some rigors that are necessary to know and avoid them. This contribution discuss some problems associated with the comparative technique used for determining joint rock coefficients.
