This research investigates the effects of foundation methods in cohesive soils, particularly

within the soft clay of Gothenburg. These soils often encounter issues such as mass

intrusion, leading to instability. The study aims to analyze suitable methods to reduce

mass intrusion in the form of horizontal movements. It includes a thorough literature

review to understand existing knowledge, as well as field studies to collect data on soil

characteristics and behavior.

The study's results suggest that adapting the piling sequence and utilizing techniques to

minimize soil movements can significantly decrease the risk of damage to existing

structures. By selecting appropriate piling methods and applying geotechnical strategies,

project safety and sustainability can be greatly enhanced.

The application of identified strategies and techniques can contribute to a safer and more

sustainable urban development in Gothenburg and other areas facing similar geotechnical

challenges. Using scientific methods and well-founded strategies, geotechnical risks can

be effectively managed, enabling safer and more sustainable urban development. This

study contributes to the overall understanding of geotechnical processes and applications,

guiding future research and practice in the area.
