Исследовалось движение обвала по склону, сопряженному с горизонтальным участком. Теоретическое исследование осуществлялось с использованием модели на основе метода дискретных элементов. Для верификации модели был проведен эксперимент на лабораторной установке. Представлено сравнение дальности пробега обвальной массы в зависимости от крутизны склона в экспериментах и расчетах. Получено удовлетворительное совпадение результатов The rockfall movement of the slope, which is associated with the horizontal section, was investigated. The theoretical investigation was performed using model, based on the Discrete element method. The experimental investigation was performed using laboratory equipment. Comparison between the experiment results and calculations were presented. Numerical calculations of the affected area of rockfall, performed for various values of the slope angle to horizontal surface, satisfactorily describe experiments
