Abstract:
Rockfall is a natural process which occurs as a result of gravity and erosion and is besides landslides, rockslides, avalanches or mudslides part of the geomorphologic dynamics in alpine areas. With the changing climate conditions, the framework conditions for natural disasters are changing too. The availability of boulders is increased by chemical and physical detachment mechanisms. Protective structures against rockfall are technical protection methodes of a protection system against alpine natural hazards. Therefore, each protective methode within the system must perform its function properly. With the steady expansion of the protection structures in Austria the portion of costs for their conservation is also increasing. To implement an effective conservation strategy as precisely as possible, knowledge of the condition of the individual protection structures is essential. For this purpose so-called damage type catalogs are needed. They categorize the different damages which can occur at the different protective structures. To assess each protective structure, periodic inspections on site are carried out with appropriate protocols. The Torrent- and Avalanchecontrol in Austria is currently creating a database for all protection structures. Meanwhile staff is trained for their further inspection work in the field. These things are important since the implementation of some new Austrian guidelines (ONR 24800 – 24810). Three types of inspection are provided in the new guidelines to evaluate the condition of the buildings so that maintenance activities can be set. They are divided into the continuous monitoring (LÜ), control (C) and examination (P). Each inspection type has different recurrence intervals and different accuracy of the investigation.
