Sicherheitsbeurteilung für Bauwerke in langsamen Großmassenbewegungen.

Translation abstract <bold>Safety assessment of buildings constructed in large, slow moving landslides</bold>Large slow moving landslides (SMLS) with typical deformation rates in a range of some mm to several dm per year and volumes of several 100,000 m3 to more than 100 mio. of m3 are common phenomenon in Alpin regions. Settlement areas, infrastructural buildings, bridges, tunnels, water reservoirs as well as protective structures are influenced in many cases by such SMLS. Whereas small landslides can be stabilized by support measures in a way that factors of safety acc. to standards can be proofed, this is often not possible for large landslides due to technical and economical reasons. In this paper, alternative verification procedures and assessment methods for building constructions in such SMLS and possible discrepancies to requirements of actual standards are discussed. Based on previous experience with practical examples, specific assessment criteria for an assessment of the use of settlement areas and structural facilities in SMLS are given depending on the change in the safety factor ΔFOS, the changes in movement rates, sensitivity analyses and the observation method.
