Hence, the proposed baffle system is more cost-effective compared with the conventional baffle system.īi, Y. For the crown-like baffle system with triangular baffles, the cumulative residual kinetic energy decreased by 6.22% with 83.94% of the concrete consumption of the conventional baffle system. The results reveal the cumulative residual kinetic energy of the crown-like baffle system with square baffles decreased by 18.75% with the same concrete consumption as the conventional baffle system. Two crown-like baffle systems were compared with a conventional baffle system based on the typical avalanche model. The influence of these effects leads to the formation and growth of cushions behind the baffles, and these cushions enhance the particle-particle interaction. Two effects, the impedance effect and the deflection effect, were identified. The results reveal more than 90% of the kinetic energy of the granular flow was dissipated by particle-particle interaction. The energy dissipation mechanism of this system was investigated based on DEM. In this paper, a crown-like baffle system is proposed to better dissipate the flow energy.

Baffle systems are usually set up in torrent channels to dissipate the flow energy and reduce the destructive effects. In mountainous areas, rock avalanches swarm downslope leading to large impact forces on structures.
