Rapid soil–boulder mixed flow commonly occurs in steep mountainous regions and has the
potential to damage critical infrastructures. Baffles are typically used as flow-impeding …

In mountainous terrain, landslide debris is a common occurrence around the world that can
potentially result in catastrophic consequences to downstream residents and facilities …

Boulders entrained in debris flows are the main cause of damage to debris-resisting
structures. Poly-dispersity leads to grain-size segregation, which causes boulders to migrate …

Channelized debris flows surge downslope in mountainous regions and have large impact
forces. Arrays of debris flow baffles are frequently positioned in front of rigid barriers to …

This study investigates the mechanism of rockfall impact against a granular soil buffering
layer above a concrete/rock shed via numerical simulations by discrete element method …

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 …

Boulders mixed with debris flows roll downstream under interactions with debris flow slurry,
which poses a great threat to the people, houses, bridges, and other infrastructure …

Baffle arrays are used to filter boulders from granular flows, such that the impact load
exerted on barriers is reduced. However, current guidelines provide limited …

Mitigation of landslide debris hazards sometimes requires the use of structural
countermeasures such as baffles to minimise the destructive impact energy of a torrent. An …

A discrete element model consisting of irregular crushable filling particles and a flexible wire
mesh is established. The numerical model is validated against the static net punching test …
