| dc.description.abstract | In recent years, there has been a growing focus on landslide hazards and risks due to the gradual increase in landslide occurrences in Norway attributed to climate and climate change. This has led to heightened attention to the safety and stability of areas prone to sensitive and quick clay formations. In these clay-rich areas, landslides typically occur on steep slopes when the clay loses its strength over time and collapses under certain loading conditions. Currently, terrain modifications through construction activities are one of the main causes of such landslides, along with erosion in streams or rivers, although weather conditions often trigger the actual landslide event. The danger associated with this type of landslide, particularly quick clay landslides, is that they often initiate small but propagate over a larger area, potentially leading to catastrophic consequences for affected communities.
The focus of this master's thesis is to assess the safety against quick clay landslides. This research problem is of particular interest due to climate projections suggesting that extreme weather events may affect the stability of quick clay areas in the future. Therefore, there is an increased need to ensure the safety of such areas. By applying the GeoSuite software, stability analysis has been performed for the current situation in the area and after appropriate measures. The analysis has been supported by interpretation and assessment of data, simple calculations as well as literature review. By applying NVE guideline 1/2019 as the foundation for the thesis, the findings demonstrated a consistent safety factor across all analyses, satisfying the requirements. | |
