BEARING CAPACITY OF SINGLE PILES IN SENSITIVE CLAYS: CASE STUDY BY THE PENETROMETER TEST METHOD

CAPACITE PORTANTE DE PIEUX ISOLES DANS LES ARGILES SENSIBLES: ETUDE DE CAS PAR LA METHODE PENETROMETRIQUE

The penetrometer test has been used to determine the bearing capacity of driven and jacked-in single piles in sensitive clays. The cases presented in this paper were carried out on two sites with steel, concrete, and wooden piles. The bearing capacities calculated on the basis of the results of penetrometer tests show that this approach has a good potential and at the same time is simple and fast. It has been possible to obtain a calibration by a comparison with the loading tests carried out on each of the piles. Taking into account the low strength of some of our clays, experience has to be gained in order to adapt the lateral unit friction curves to our clays. This approach also has the advantage of allowing the determination of the bearing capacity of wooden piles and of taking into account the conical effect when determining the lateral friction component.
