      <abstract xml:lang="ru">
        <p>Структурная ослабленность горных пород изучается в настоящее время в разных аспектах. Разнообразие стоящих при этом задач обуславливает боль­шое число методов исследования. Большинство из них обеспечивают только косвенную оценку ослабленности массива и не дают количественных зависи­мостей влияния ослаблений пород на их прочностные и деформационные харак­теристики в условиях естественного залегания.</p>

        <p>Structural weakening of rocks is currently studied in different aspects. The diversity of the tasks involved determines a large number of research methods. Most of them provide only an indirect assessment of the weakening of the massif and do not give quantitative dependencies of the influence of weakening of rocks on their strength and deformation characteristics in the conditions of natural occurrence.</p>
