<p>The present invention relates to a method for evaluating a texture using distribution characteristics of a volumetric strain curve of granite comprising: a rock block collecting step to collect a square rock block from granite; a rock block surface cutting step to cut a surface of the rock block in a direction parallel to three texture surfaces; a rock block dividing step to divide the rock block into a plurality of square rock samples; a core specimen manufacturing step to manufacture each core specimen in a direction perpendicular to three texture surfaces in the rock sample; a stress applying step to apply stress with respect to the core specimens; and a texture quantitative evaluation step to obtain a stress-volumetric strain curve by calculating volumetric strain (ε_v) for each texture by measuring dynamic response according to the stress applied to the core specimens, to divide a rock fracturing step through the stress-volumetric strain curve into four steps of strength sections (I, II, III, and IV), to divide a linear section having a form of a straight line into IV-2 section in the stress-volumetric strain curve of IV step among four steps of strength sections, to analyze distribution characteristics of the stress -volumetric strain curve in the corresponding IV-2 section, and to evaluate relative strength with respect to three texture surfaces.</p> |
