Study of confinement effect in geocells
Résumé
Recent studies have proved that the cell and the enclosed soil behave essentially as a unit, having higher properties than the content alone. In order to explain the effect of geocells as a reinforcing member and the mechanism of confinement, tests using large scale and small scale specimens were carried out. Study of the cells size upon the size of footing is presented. The result of rigourous finite element analysis are compared with a standard analysis. As a result, numerical simulation were consistent with loading tests, and it was confirmed that the both analysis: finite element which considered the discontinuity and standard method which considered an homogeneous material were effective analysis method for geocells.
