Backanalysis of sheetpile wall test Karlsruhe (1993) applying inverse analysis

The Finite Element modelling of sheetpile walls has been evaluated in the light of the measurements of the 1993 sheet-pile wall in Karlsruhe. The method applied is a simplified version of the Maximum Likelihood approach, as used by Ledesma (1989), applying the Inverse analysis equations and FEM analysis subsequently. A reasonable fit for stress and displacements was found, including the force deformation curve for the strut, which was not a part of the fit. The soil stiffness based on the laboratory test result seemed to have under estimated the in situ stiffness, as observed, largely.
