Abschätzung einer Anprallkraft für murenexponierte Massivbauwerke

Estimation of a debris flow impact force against protection structures made of structural concrete. Alpine regions are exposed to several gravitational hazard processes. Such processes are debris flows, landslides or avalanches. Human settlements are amongst other things protected by structures adjusted to a certain process. The preparation of methods of calculation for the estimation of a debris flow impact force against such protection structures made of structural concrete is the major content of this paper. The paper is strongly related to the Austrian code series ONR2480X currently under development.
