Boulders entrained in debris flow induce high impact forces on a rigid barrier. In current
design practice, the concentrated load from boulders is estimated using the Hertz equation …

Coarse grains accumulate at granular flow fronts and must be considered when studying
granular flows impacting barriers. Experimental studies often use instrumented barriers …

Expanded polystyrene (EPS) geofoam presents a promising application in the protection of
galleries against rockfall. This paper focuses on experimental and numerical studies that …

Rock-filled gabions are commonly installed in front of reinforced concrete structures to
reduce concentrated impact loads induced by rock fall and boulders entrained in debris …

Granular matter exists widely in natural environments, industrial production, daily life, and
biological science. Great attention has been attracted because of its peculiar mechanical …

This study is devoted to understanding the impact of irregularly shaped rock blocks against a
soil buffering layer above a rock shed via numerical simulations by discrete element method …

Rigid barriers are prevalent structure countermeasures for mitigating granular flow hazards
in mountainous areas. To reduce maintenance for barriers, a basal clearance is commonly …

Soil cushion layers are commonly paved in front of protection structures to avoid the direct
impact of rockfall and debris flow. This study is devoted to investigating the influence of …

The coal seam and the roof of the roadway bear loads together in the underground
engineering of coal mine. Especially for the roadway driven along the roof, its deformation is …

Rock-filled gabions are used to shield barriers and galleries from boulder fall in
mountainous regions. A challenge in the design of rock-filled gabions lies in the estimation …
