Abstract

This report presents a preliminary study of possible mechanisms involved in impact of debris flows on flexible landslide debris-resisting barriers and the dynamic interaction process. This report covers a review of design approaches put forward in the literature and adopted by the construction industry for debris-resisting flexible barriers. Based on insights from results of physical experiments and advanced numerical models, two possible debris deposition mechanisms involved in the impact of landslide debris on flexible barriers are identified. The observations may help designers to gain a better appreciation of the possible dynamic interaction between a debris-resisting flexible barrier and the landslide debris, and provide a basis for further development work in this subject area.
