BIG A2020-09 Förenklade stabilitetsanalyser i ett förändrat klimat

项目名称：	BIG A2020-09 Förenklade stabilitetsanalyser i ett förändrat klimat
摘要：	The stability of slopes will be significantly impacted by climate change, and already now the foreseen cost of mitigation measures is significant. Slope stability analyses are performed routinely with Limit Equilibrium method (LEM), which is not ideal for assessing climate effects and the consequences of possible mitigation measures, in particular for slopes in sensitive clays. Forensic analyses of slope failures in clays suggest that the trigger for failure is most often due to changes in pore pressures and topograhpy (erosion). Furthermore, as research in an ongoing BIG project suggests, the role of the initial state is of paramount importance on the emerging soil strength, and the resulting stability of the slope. Thus, we need methods for effective stress based stability analyses, in contrast to the total stress analyses currently used. In addition, the complexities of natural and man-made slopes (including embedded structural elements and complex geometries) need to be captured to some degree. Therefore, we propose to use advanced FE analyses to understand and quantify the associated problems, and then translate the findings to an updated effective stress based approach that is simple to use for practitioners. All stakeholders (researchers, consultants, contractors) as well as major clients such as SGI and Trafikverket, will directly benefit from the project, which aims to offer a well-documented method for the assessment of slope stability in a changing climate.
