説明

A test pit work was carried out in 2007 in the area of the Extension of Mariinsky Theater in St. Petersburg, Russia. A sheet pile cofferdam was applied to the work. In the work large displacement of sheet pile was measured. We analyzed this work by the elasto-plastic FEM in total stress condition. In this study Mohr-Coulomb type yield function and Drucker-Prager type plastic potential were applied to constitutive equation. We decided the cohesion of each soil layer from the geological column and the Young's modulus of the strut and sheet pile not to be able to get the detailed soil parameter and the sheet pile and strut data. For this analysis it was obvious that the ineffective strut became a factor of the measured large displacement of the sheet pile.
