Investigations of Pile-Soil Interaction in Cohesive Soils-PPT Presentation

PPT Presentation

Pdf Summary

The presentation, “Investigations of Pile–Soil Interaction in Cohesive Soils,” was delivered by Moritz Anton Loreth, Andre Vogel, Sascha Henke, and Helmut Schmidt University at the International Conference on Deep Foundations and Ground Improvement in Berlin, May 18–20, 2022.<br /><br />It describes physical modelling and laboratory observations using a new device for measuring friction under torsion. The device comprises a transducer, friction surface, pressure cell, rotating frame, gear, and electric motor. Results are presented as shear force and shear moment in relation to horizontal displacement under an applied load of 226 N/m.<br /><br />The presentation also introduces a one-dimensional constitutive approach. It shows shear stress and moment in relation to shear strain for the same applied load. The supplied material identifies the experimental setup and types of measurements, but does not provide numerical results or detailed conclusions.
