Investigations of Pile-Soil Interaction in Cohesive Soils-Video

Video Transcription

Video Summary

Moritz Lohret presents research on pile–soil interaction during the installation of open-ended piles in cohesive soils, focusing on contact behavior and plug formation. The study combines laboratory physical modeling with development of a constitutive framework. A new testing device integrates ring-shear and compression tests to measure forces, moments, and shear behavior under applied pressure. Initial results show relationships between shear stress, shear strain, and mobilized surface friction angle. Future work will extend the framework using hyperplasticity for clay and apply it in numerical analyses with both continuous and discontinuous methods.
