The particle breakage of angular and porous calcareous sands at high strain rates (HSRs) is important but rarely quantified. This paper conducts a series of split-Hopkinson pressure bar …
Light-weight flexible steel net barriers catch coarse debris, but let some of the fine material and water pass through the net. They are difficult to design so that they can withstand the …

Engineering accidents of bridge pier damage and collapse incurred by debris avalanches frequently occur in mountainous areas. This paper presented a three-dimensional DEM …
In the design of multiple rigid barriers, the height of the first barrier governs the impact dynamics of debris flow on the next barrier in a channel. However, current design …
