Debris-flow disaster has caused large casualties and tremendous economic loss. Check
dams, flexible barriers, silt dams and baffle arrays are most used disaster prevention …

The impact behavior of superspeed granular flows is not sufficiently understood, although it
is the basis for establishing an impact model, which is important in barrier design. Centrifuge …

Slit dams are widely used for managing multiphase geophysical flows with diverse
objectives. However, quantitatively linking dam configurations and flow properties to design …

Rapid granular flows are one of the most catastrophic geo-disasters frequently encountered
in mountainous areas. The baffle structure has been demonstrated to be an effective …

Baffle structure, a promising countermeasure in reducing the destruction power of rapid
granular flows, needs more investigation especially with focus on the physically based …

Baffle system is a promising disaster mitigation measure, while the mechanism of debris-
baffle interaction at grain scale has not been fully understood, and especially the effect of the …

Granular flows, such as rock avalanches and debris flows, are gravity-driven and often hit
engineering structures that are placed in their paths, generating dynamic impact pressures …

The pile-anchor structure is widely used in slope/landslide reinforcement, and is also
applicable to debris flow and rockfall barriers in mountainous areas. However, the impact …

Debris flow is a common geological hazard in mountainous area. The large boulders carried
by debris flow can be particularly destructive to downhill facilities. Constructing steel baffle …

In this paper, we present a numerical study of dynamic behavior of rock avalanche by using
three-dimensional particle flow simulation. The emphasis is put on the influence of particle …
