Abstract EN
The failure of debris dams impacted by the massive stones in a debris flow represents a difficult design problem.
Reasonable materials selection and structural design can effectively improve the resistance impact performance of debris dams.
Based on the cushioning properties of expanded polystyrene (EPS) concrete, EPS concrete as a buffer layer poured on the surface of a rigid debris dam was proposed.
A three-dimensional numerical calculation model of an EPS concrete buffer layer/rigid debris dam was established.
The single-factor theory revealed change rules for the thickness of the buffer layer concerning the maximal impact force of the rigid debris dam surface through numerical simulation.
Moreover, the impact force-time/history curves under different calculation conditions for the rigid debris dam surface were compared.
Simulation results showed that the EPS concrete buffer layer can not only effectively extend the impact time of massive stones affecting the debris dam but also reduce the impact force of the rigid debris dam caused by massive stones in the debris flow.
The research results provide theoretical guidance for transferring the energy of the massive stone impact, creating a structural design and optimizing debris dams.
