Tensar Academy : Site Investigation Techniques for the Design of Embankments Built Over Soft Clays
The webinar covers site investigation techniques for embankments built over soft clays, including stability and settlement assessment. It emphasizes the importance of undrained total stress parameters for stability assessment and careful sampling and testing for embankment behavior assessment. The presentation discusses the impact of sea level changes on the behavior of upper and lower marine clay, as well as the challenges in obtaining reliable results from triaxial tests. It also explains the settlement process of an embankment on soft clay, including instantaneous distortion, consolidation settlement, and secondary compression. The comparison of predicted settlement values with actual settlement results highlights the difficulty of making predictions for embankments over soft soils and the importance of an excellent site investigation and appropriate interpretation.
