Abstract
Способ исследования образцов горных пород, включающий воздействие на образец горной породы (образец) внешним давлением, измерение величины скорости распространения продольных и поперечных упругих волн в образце, отличающийся тем, что производят циклическое воздействие внешним давлением на образец с чередованием нагрузки-разгрузки с постепенным увеличением внешнего давления до номинальной величины, о достижении которой судят по моменту стабилизации зависимости скорости распространения продольной и поперечной волн от увеличения внешнего давления на образец, в результате полученные значения скорости распространения продольной и поперечной волн используют как истинные величины для расчета значений модуля Юнга и коэффициента Пуассона.A method for studying rock samples, including external pressure acting on a rock sample (sample), measuring the propagation velocity of longitudinal and transverse elastic waves in a sample, characterized in that the external pressure is cyclically applied to the sample with alternating load-unloading with a gradual increase in external pressure to a nominal value, the achievement of which is judged by the moment of stabilization of the dependence of the velocity of propagation of longitudinal and transverse waves from an increase outside pressure of the sample, as a result, the obtained values of the propagation velocity of the longitudinal and transverse waves are used as true values for calculating the values of Young's modulus and Poisson's ratio.
