Recalculation of in-situ CPTu in intermediate soils using G-PFEM

Research output: Chapter in Book/Report/Conference proceedingConference paperpeer-review

Abstract

Piezocone penetration in intermediate soils is often associated with partially drained behaviour which has to be taken into account when interpretating the results. As part of the research project PITS, the effect of partial drainage on in-situ testing in postglacial silty deposits in Austria is investigated by means of in-situ testing campaigns, laboratory testing and numerical simulations. The present work presents a numerical recalculation of in-situ CPTu, carried out with different penetration velocities in a silty soil layer at the test site Rhesi near lake Constance, using the application G-PFEM. The results agree reasonably well with the in-situ measurements considering the given heterogeneity of the soil layer and suggest that partial drainage occurs during the penetration process.
