Das Projekt "Interaktion Strasse-Hangstabilität: Monitoring und Rückwärtsrechnung" wird vom Umweltbundesamt gefördert und von Eidgenössische Technische Hochschule (ETH) Zürich, Institut für Geotechnik durchgeführt. The following objectives will be achieved in the proposed research:
Objective 1: Identification of the landslides in Switzerland suitable for the simplified analysis and development of the database of the observed data.
Objective 2: Development of the inverse analysis procedure for prediction of effects of environmental factors (including transportation) on the landslide evolution.
Objective 3: Development of the recommendations for the optimum landslides monitoring programs as related to the road and railway construction and operation.
The goal is to develop a state-of-the-art procedure for analysis of long and short term effects of different environmental factors (including the road and railway construction and operation) on landslide evolution and stability. This procedure will be based on the inverse analysis of the monitored landslide displacements with the landslide being used as a gigantic 'strain gage' to interpret its displacements for mapping the shear and normal stresses on the slip surface and in the sliding body. As the first step towards this fundamental goal, in the proposed project the development will be limited to the analysis of selected landslides in Switzerland, which can be studied using an infinite slope model.
