      <abstract xml:lang="ru">
        <p>Представлены результаты экспериментальных исследований прочностных свойств горных пород применительно к оценке устойчивости бортов карьеров. Получены формулы, описывающие взаимную связь между показателями предельной и остаточной прочности образцов горных пород и остаточной прочности при сдвиге вдоль поверхностей ослабления. Разработан новый расчетный метод определения показателей остаточной прочности горных пород при сдвиге вдоль поверхностей контактов по данным испытаний малогабаритных монолитных образцов встречно направленными сферическими инденторами. Предложена методика оценки расчетных показателей прочности (коэффициентов структурного ослабления и углов внутреннего трения) трещиноватого прибортового массива. Методика основана на данных испытаний на раскалывание малогабаритных монолитных образцов сферическими инденторами с учетом контактных условий вдоль поверхностей ослабления и доступна к применению в полевых условиях. Допускается использовать при испытаниях образцы неправильной формы.</p>

        <p>The paper presents results of an experimental study on strength characteristics of the rock mass as applied to the assessment of open-pit slope stability. Formulas have been obtained that describe a correlation between ultimate and residual strength of rock samples and residual shear strength along the weakening surface. A new method has been developed to calculate residual interface strength of the rock mass basing on data from the examination of small-scale monolith samples with opposing spherical indentors. A method has been proposed to estimate strength characteristics (structural weakening coefficients and internal friction angles) of the fractured near-slope rock mass. The method relies on test data from shattering small-scale monolith samples with spherical indentors, taking into ac- count contact conditions along the weakening surface, and can be applied in the field conditions. It is acceptable to use irregular-shaped samples in thetests.</p>
