Abstract

The work seeks to address ways of obtaining the impact forces of Brazilian debris flows, mainly arising from the portion referring to rock blocks, a non-viscous portion, of the movement. A methodology is proposed that uses numerical tools such as DAN3D and RocFall to obtain the impact forces of rock blocks in static and dynamic containment structures. To obtain the results, we sought to apply the methodology in three recent cases, of important debris flows that occurred in Brazil, located in Serra do Mar, more precisely in the municipalities of Nova Friburgo and Teresópolis in Rio de Janeiro and in São Sebastião in São Paulo.
