Felsen in danger: Experts warn of fire consequences in the Elbe Sandstone Mountains
The Freiberg geologent team has been investigating the stability of rocks and the dangers that come from the mountains since the devastating fire in Saxon and Bohemian Switzerland in 2022. Touristically used areas such as the Elbe Sandstone Mountains are the focus of this research. According to a message from TU Bergakademie Freiberg analyzed. This work is part of two projects that deal with mass movements in mountains.
Together with the KarlsUniversität Prague, the internal structure of rocks was also examined, especially at the woe tower of the Rathen Felsenbühne. These research projects are supplemented by cooperation with the HTW Dresden, in which mass movements, infrastructure risk and the stability of embankments in the Caucasus are examined. The data collected flow into a geographic information system (GIS) that serves to develop security concepts.
fire attempts and geotechnical models
There is a special focus on the "Firerisk" project, which deals with non -fed sandstone rocks in the Elbe Sandstone Mountains. These rocks have a fixed sandstone cover and a loose sandy inside, but so far there are only a few knowledge of their structure and distribution. In order to determine the materials of the sandstone, large -scale fire tests with different temperatures and time duration are carried out. The results obtained from this are crucial for the creation of geotechnical fire models that can calculate the behavior of rocks and rubble through different fire scenarios.
In view of the risks that arise from mass movements, the documentation of the initial state and the changes in rock walls in endangered areas and the assessment of the hazard by experts are particularly important. The Geology Sachsen recommends measures such as collecting crashed stones of walk-in slopes and planting stone chilling protection for braking falling stones.preventive measures and engineering geological examinations
In the case of new buildings in endangered areas, caution should be possible. Simple structural measures on buildings are often not sufficient due to the large moving masses. IngenieUrgeological detailed examinations are required to precisely estimate the risk situation. When reduced stone cheating, precautionary measures such as the massive construction design of the slope -side wall and the roof as well as the reduction of the number of windows are recommended.
In addition, targeted protective fences can increase safety below rock walls and a suitable terrain modeling by leaking or collecting walls. A drainage of slides at risk of slipping can also contribute to stability. The maintenance of a protective forest on the slope serves to prevent flat -level slides and slope breaks.In view of the increasing extreme weather events and the dense settlement in mountains, the Geori's project explains strategies for monitoring rock slopes. High -resolution photogrammetric measurement methods play a central role in monitoring stability development.
The project is funded by the Free State of Thuringia and the European Union and runs in cooperation with the engineering office for Geotechnik Prof. Witt & Partner and the Trigis Geoservices GmbH, such as reports about it . The aim is to make the risks predictable through precise, comprehensive and objective location assessments and thus to implement targeted security measures at the focus of risk.
