Short summary
This study presents the large-scale test results of dry granular flows impacting a flexible barrier. Motions and deposition characteristics of granular flows are described and analysed. Impact forces on the flexible barrier directly and on the supporting structures are measured and compared. It is found that the flexible ring net can reduce the impact force from a granular flow with large deformation. Furthermore, existing simple approaches for impact force estimation are verified.
