Identification of Landslide Susceptible Slopes and Risk Assessment Using a Coupled GIS-FEA-Module
Periodically, natural disasters like landslides cause many casualties and great damage. Therefore warning systems have been developed to protect people and goods. But to be able to set-up and to apply these systems, landslide susceptible areas need to be identified first and appropriate methods for hazard and risk assessment must be available. In the research project a coupled module, consisting of a geographical information system (GIS) and a Finite-Element-Analysis-tool (FEA) for the investigation of slopes has been developed. Therewith, potentially unstable slopes can be analyzed from a geotechnical point of view. Physical processes, which may lead to slope failures and may cause the development of landslides can be investigated in detail. Moreover, the possibility to define criteria indicating slope failure and to determine critical magnitudes of events is supported by the module. The set-up of geotechnical models for FE-Analyses is supported by the GIS as well as the evaluation and visualization of the computation results. Advanced visualization and analysis methods, regarding the hazard and risk assessment of slopes are merged in a decision support system, which is integrated in the GIS to support decision-makers in time.
