Experimental validation of a new semi-empirical impact force model of the dry granular flow impact against a rigid barrier

YJ Jiang, XY Fan, LJ Su, S Xiao, J Sui, RX Zhang… - Landslides, 2021 - Springer
The maximum impact force of granular flow and its action point on a rigid barrier are the key
indices of the anti-slip and the anti-overturning calculation, respectively. On the basis of the …

Merging terrestrial laser scanning technology with photogrammetric and total station data for the determination of avalanche modeling parameters
