Аннотация


Исследован механизм разрушения и выполнена оценка устойчивости сейсмически обусловленного оползня вдоль скоростной магистрали Ваньчжоу-Ляньпинь в Китае. Показано, что основной причиной нарушения устойчивости склона является его исходная геометрия. Расчеты показали, что потеря устойчивости скального склона после землетрясения Вэньчуань, в основном определялась глубинным сдвигом. Предложены методы по стабилизации неустойчивых участков.
