Fourier method for evaluation of irregularity of rock joints

Popis výsledku v původním jazyce

The Fourier two-dimensional series is used for classification of surface irregularities ofrock joints. The expansion coefficients of this series are employed to form an absolute indicator of waviness of joint rock surfaces. The indicator serves for classification of surface irregularity of rock joints. The method has been applied to several real rock samples and the results are presented in the form of graphs. A similar visual comparison is often performed in geotechnical practice when joint rock coefficients are determined by means of database surfaces. Visual and numerical results have been found in good agreement and this fact supports soundness of the suggested Fourier method aimed at classification of surface irregularity of rock joints. The computerized method which is presented in this contributions is based on two absolute numerical indicators that are formed by means of the Fourier replicas of rock joint profiles. The first indicator quantifies the vertical depth of profiles and the second indicator classifies wavy character of profiles. The absolute indicators have replaced the formerly used relative indicators that showed some artificial behavior in some cases. This contribution is focused on practical computations testing the functionality of the newly introduced indicators.
