Etude de la stabilitè d'ensemble des rideaux de soutènement ancrés
Laboratory tests on a two-dimensional model of an anchored sheet pile structure are carried out to study the displacement field of a soil-structure system. The comparison of the experimental results with those obtained by the Kranz method shows significant differences. The overall stability analysis of these structures is then investigated by a theoretical model using the upper-bound method of the limit analysis theory. A translational failure mechanism is considered for the calculation scheme. This mechanism is composed of two rigid blocks in the active zone and the so-called log-sandwich mechanism in the passive zone. Numerical results show good agreement with results obtained from laboratory tests.
